I have downloaded live server but it is not working. It doesn't show me any error messages like it does to others. I tried reinstalling it, I tried reinstalling vs code too, but nothing happened. I see from people which have it working that it displays on the tab of the IDE but for me it’s not there. I try to open it with right-clicking on one of the HTML files but nothing happens. I also checked my default browser and added it to the json.file.
I just decided to install an earlier version of the live server extension and it worked.
I went to open a repo using Vs Code on a remote ssh host. I can ssh in successfully but when I try to open a repo I get Failed to connect to the remote extension host server (Error: Handler already set!). I've tried un installing and re installing Vs Code. Does anyone have a fix other than switching ides.
avenmore comment helped me:
I started getting this message with v1.57.0 when trying to run a Vue
project. Long story short: I usually have my DEBUG CONSOLE window
docked inside to the right of my TERMINAL (powershell), and upon
opening VSCode it wouldn't be visible and I'd get this message after
building successfully and trying to launch. The work-around is to
close VSCode, navigate to folder
USERPROFILE%\AppData\Roaming\Code\User\workspaceStorage and delete the
contents (notably state.vscdb) and then restart VSCode. The DEBUG
CONSOLE then shows itself again and all is fine unless I dock it again
and close VSCode and there is a good chance of it happening again next
time VSCode is opened. I have stopped docking the window inside the
terminal and it hasn't happened since.
For me what solved this was to go into the 'remote explorer' and clear out the SSH Targets that I already had in there before the upgrade, and then just paste them in again. Now I can connect. For example, a re-pasted SSH command looked like:
ssh -i "/Users/myuseraccount/abc.pem" someuser#ec2-ip-instance1.compute.amazonaws.com
A few days later this stopped working again. I think maybe because my SSH targets config saved what I pasted in as my SSH connection command. It appears "sometimes" if there are any entries in the SSH target config file, that this error occurs.
I find to ensure this error never occurs do
rm ~/.ssh/config
every time before you open Vs Code. Assuming ~/.ssh/config is where your Vs Code is reading its SSH entries from. There is one other place possible under /etc/$somewhere (I dont know where).
Then when you go to your empty SSH Target and hit the (+) button to connect, paste in the entire ssh connection request at the top of this file. I think you have to clear out the SSH targets every time otherwise I get this error coming up again days later.
Try in settings.json add item "security.workspace.trust.enabled": false
Windows, VSCode 1.57.1
I've just remove and added the host again in ssh configuration:
If you are using MacOS, I found a way.
Close Visual Studio Code, delete files in these two folder, then restart Visual Studio Code.
rm -rf $HOME/Library/Application\ Support/Code
rm -rf $HOME/.vscode
I tried all solution on this post, and can't get success. Then cloned another repo on my WSL folder then open, it was fine. So I changed my repo name, then problem gone. Maybe it may dumb solution. But it works me.
You gonna have to change the "debug.terminal.clearBeforeReusing" to true on setting.json. It works for me
I noticed there was a workspace folder in the folder above, deleted that and it resolved the issue
On the remote system, after various things had happened, I did mv .vscode .vscode-old to basically reset the remote .vscode (over ssh). I had also renamed the remote folder for the project -- not sure if that matters. Then I was was able to connect to it again.
I can't be scientific about those "various things that happened", but I'll to list some:
I had created a second project alongside the first and had connected to it - this was for unrelated reasons and preceded the "handler" error
it was then that I had issues connecting to the first one, even though it had worked for months and months without me ever having this Handler already set error -- related to creating the 2nd one? Not sure. The 2nd one worked fine throughout.
I tried File: Open Folder... from the second remote project and opened the first; it opened but got 2 python exception errors in a python extension - unfortunately I can't remember what they were. This could be noise / unrelated. I happen to have both MS python and pylance extensions installed remotely, I think it was the pylance once that was not happy.
during this, I had also renamed the 1st folder which didn't work; I'm not sure if the rename triggered the different behaviour ie python ext errors instead of the "handler" error
I then replaced .vscode in the first remote project (with the new folder name)
... and that was when it worked, with no "handler" error and no complaints from the python extension(s)
I installed and configured the Apollo GraphQL extension in VSCode. It worked perfectly.
However, when I close and reopen VSCode it doesn't load. The icon never shows up and nothing loads in the console output.
The extension is definitely loaded because syntax highlighting still works but we get none of scheme features.
I tried
uninstall/reinstall of the extension.
closing vscode, deleting the extension folder directly, reinstall extension, restart vscode.
installing the Insiders Edition of vscode and installing the extension there.
In all cases it works the first time but not after a restart.
How can I troubleshoot/fix this issue?
I have been looking around and I haven't found any answers to my issue.
I keep getting this error "Extension host terminated unexpectedly." and I have tried removing all of my extensions, reinstalling the program, trying different versions of vscode including the insider versions.
The way I get this isssue isn't from trying to use the debugger or trying to use some sort of extension, as I said before I removed all of them and the error keeps on coming back, it's simply from opening the application. I'm not entirely sure how to continue? I have had to use another editor because the error just doesn't go away. I will just have to wait for another update of Visual Studio Code I assume? I've had the issue since tuesday this week, guessing since the latest update.
Above is the error message I get. It is closed by esc but reappears very shortly after, every time.
When I open developer tools, this is what I find in the console.
Running vscode from command prompt with Code.exe --disable-extensions doesn't help.
Visual Studio Code version: 1.16.1
I appreciate any help.

I had the same error after updating vsc to v. 1.31.0.
Disabling Live Server Extension worked for me.
Here's the error i'm getting having the extension enabled.
I started getting this error when vscode automatically updated to March 2020 (version 1.44). I have tried various suggestions given in the forum and over the internet but none of them worked.
What worked for me: I downloaded January 2020 (version 1.42) build from https://code.visualstudio.com/updates/v1_42 and ran over the previous installation without uninstalling and surprisingly, the error disappeared and all extensions are loading and working properly.
I tried following things and non of them worked:
I disabled all the installed extension from GUI.
uninstalled all the extension and installed again.
removed the left-over extensions from Windows %USERPROFILE%.vscode\extensions.
tried launching from the command prompt with --disable-extensions option.

It ended up being one of the base extensions that runs on startup that was the root of the problem.
In my case the git in extensions folder was causing it.
"git.enabled": false was not doing the trick so I had to remove the git folder altogether for the error to disappear.
In my case, I used typescript-hero extension. Disabling this extension fixed my problem.
It's temporal fix but maybe will help somebody.
I disabled all the extensions with name Live for example Live Server, Live Share etc and restarted my vscode again and it worked for me.
For me this was happening due to HTML CSS Support extension. so i removed it and restarted vs code and voila! it worked!
I had to uninstall few extensions related to Java (debugger for java, Test runner for java, extension pack for java etc) to make the error go away.
Click on the developer tool option that popups and see if it has the extension which is causing this error.
I got same issue and it was because of Color Highlight Extension. I just uninstalled Color Highlight Extension and its working fine and NO ERROR.
Me too. My failure has no "Code":
Extension host terminated unexpectedly. Code: null Signal: SIGABRT

I recently ran into the same error message after accepting a permission to run a program on the extension livepreview. It corrupted all other extensions where it could not find the commands. I deleted all extension files and reinstalled the other extensions without a problem. I tried liveserver again but It never prompted me again for permissions and still, the error message keeps occurring. I'm assuming liveserver was trying to ask the computer permission to run a local server after which is still accepted but something else is interfering with the computer being able to translate from the program to actually building and accessing the local server.
In my case, the live server extension was causing this issue in 1.31.0v of VS Code. After uninstalling the extension it started working correctly.
In my case it was from the extension "Todo Tree". It was breaking on a particularly large file in my project (13.7mb), with the error saying the file was over the max-size for a node-buffer (used by the C regex matcher).
Resolved the issue by disabling the extension.
I also opened an issue for it here: https://github.com/Gruntfuggly/todo-tree/issues/135
I had same problem with following error in my VSCode console.
`1: node::DecodeWrite
2: node::InternalCallbackScope::Close
3: v8::internal::VirtualMemory::TakeControl
4: v8::internal::PerThreadAssertScope<4,1>::PerThreadAssertScope<4,1>
5: v8::internal::operator<<
6: v8::internal::operator<<
7: 00000073ECF04481`
I solved it by uninstalling Angular Console extension. Not sure if it was that particular extension or some other memory issue but problem went away as soon as I uninstalled that.
Remove all Extensions which are located in a per user extensions folder. Depending on your platform, the location is in the following folder:
Windows %USERPROFILE%\.vscode\extensions
macOS
~/.vscode/extensions
Linux ~/.vscode/extensions
Restart vscode and start installing extensions.
I am not sure why this caused , but the Antivirus was throwing popups that something like extensionprocess.js file was repaired.
Disabled the Antivirus and re-installed Vscode and it was back to normal.
Hope this helps.
Here is what helped me:
Ctrl+Shift+P --> type: "Disable"
and click Disable all installed extensions
(alternatively click Disable all installed extensions for this Workspace)
Then go to extensions panel on the left and re-enable slowly those that you really need.
See which extension (or their combination) triggers that error.
It will be highly appreciated which extenstion/combination you'll find guilty as there may be several of them, and different in time...
for me, it was code runner extension I just disabled it.
Whenever you start a debugging session in vscode to test an extension under development, a warning is shown in the Extension Development Host that your extension will be overwritten (if you have it also installed normally, e.g. the currently published one). After a while this warning really gets annyoing and I wonder how to suppress it. Anyone knows?
Update: a while ago I opened a feature request for this on Github.
This warning was been removed from VS Code in v1.37:
