Every once in a while, some of the blueprints in my UE4 project will stop working. When I try to open them, I get this screen:

I have found no way to fix this except remaking the blueprint from scratch. Is this a bug or am I doing something wrong?
I'm not sure why this problem happens, but it might be just a Mac problem.
The solution is clicking
Window -> Class Defaults -> Open Full Blueprint Editor.
(On the top menu bar)
Hope this helped. I got the answer from Epic Game's Forums

I can't type in the Unity inspector or rename any object. I tried clicking in many different areas recommended from the web. Note that this is not an error, but something I simply can't do. Is there any settings I need to turn on or off?
There are two ways to fix this:
Solution A
Go to layout then set the layout to default, it's like resetting the unity.
Solution B
Restart unity, just Close the Unity editor and open the project again.
Hopefully, one of these helps you.
I've got a problem that is seemingly impossible to debug. My project originally started using 2019.2 and upgraded to 2019.3 without any problems. I then installed the preview package for the new input system.
This "disabled" all the buttons in that they are visible in the editor and during run time but they are impossible to click on or interact with.
To reproduce this issue I tried:
Creating a new empty 2D project
Installing and switching to the new Input System
Importing their demo scene from the package manager
At this point I tried running each scene. All of them worked except "SimpleDemo_UsingActions.unity".
I added a button to the "SimpleDemo_UsingPlayerInput.unity" and added a script to the button. With a function:
public void Button()
{
Debug.Log("Button Pressed");
}
I ran this scene and it worked! I could move around shoot the cubes that is built into the script and I could click on the button and it showed in the log.
For this reason I am stumped. I do not know how to debug this issue.
Can I have some advice? Has anyone had a similar issue or know how I would go about debugging this?
I managed to find the answer. For some reason using the new input system's "InputSystemUIInputModule" breaks all the UI and just does not work.
I fixed it by just deleting my EventSystem and creating a new one in the scene.
Do not. and I repeat. Do Not use the new input system's manager for the event system.
I write answer because it's first result in google.
To get rid of this, select EventSystem in hierarchy, then in inspector you should see warning and button to replace old input system with new.
Unity ver. 2019.4.1
Input System ver. 1.0.0
I'm still currently testing but I manage to get something by duplicating the defaultInputActions.inputactions file from the Packages >> Input System >> InputSystem >> Plugins >> PlayerInput.
I realized that that .inputactions has a UI Action Maps. I added more Action Maps and did some testing, the added action maps works and buttons are somewhat reacting as well.
Just sharing this now so that more developers can test this with me and hopefully find a way to work around this major issue.
Had the same issue. Make sure that the input system package, does not have any devices inside... It worked for me after migrating from the Previous Input System
I can't find the component tabs anymore. It shows here that the component tab is opening but actually it isn't. I've cleared all the window but this tick of components tab still exists. Now my code is broken and I can't link the new tank barrel to the Tank_BP blueprint class. What should I do? Try resetting layout and even reinstall Unreal but it still didn't work. Any help will be appreciated!

Are all actor blueprint editor view all the same as you described? Did the log report some errors about that?
I think maybe there is something wrong with your editor, several ways to solve youre problem:
+ If you are using the installed version(which is installed from Epic Games Launcher),just try to use verify to repair your editor.
verify entry
If you are using the compiled version, just try to debug the blueprint editor module.
I recently installed new C/C++ software plugins for Eclipse. After restart, the perspective changed. I didn't like the new colors and stuff, so I got rid of it via Preferences->General->Appereance->Restore Defaults.
There's only one thing left thats bugging me, it's really a minor issue but nevertheless I'd like to have it fixed. The project explorer went kinda smooth and round, before the changes it was edgy. Same with the tabs. Searched the web, couldn't find an answer. Anyone?
Here's a picture
Toggle this setting within General Preferences:
I am having a problem in Eclipse where it freezes whenever I add a period (to try to bring up the content assist popup with possible methods). I can move the mouse, but the blinking text cursor disappears, I can't switch tabs or save, and I need to use a task manager to close Eclipse. This happens with all Java projects/files.
I have never had a problem like this with Eclipse before, and can't tell what started it. After doing several Google searches, all I found was this bug. However, I don't see a solution and am running Windows 7, not Linux. Also, I have never heard of Xulrunner. Does anybody have a solution or explanation? Is it an Eclipse setting, or a problem with my computer?
Error Log: https://dl.dropboxusercontent.com/u/101364250/eclipse_freeze.log
When I watched the error view, it seemed to output "Unhandled event loop exception" a lot.
For now, I have disabled the content assist, which seems to fix the problem.
However, this feature is very helpful, so any answers are appreciated!
Try opening Preferences and tick "Suspend all validators".
Try disable the hovers feature:
eclipse menu: Wndow > Preference
