My unity project gives error when i try to open it? - unity3d

I use Unity Hub 3.3.0 and 2022.1.23f1 editor version
How can I open a unity project for Mac?

I'm sorry, probably the part in the photo where the error is, I think the troubleshooting steps you wrote
unopened file
more
solutions that can be applied if it is a file that has been opened before, but I have not been able to open a file since I first uploaded it.

The type or namespace name 'UniRx' could not be found on Unity

I pretty much looked everywhere... but couldn't find anything that could debug my problem.
The only thing I do in a script is "using UniRx" to have the following error : The type or namespace name 'UniRx' could not be found.
What i tried:
On Unity, downloading from Package Manager with "Add Package with git URL"
On Unity, downloading from Package Manager with the normal way: Download -> import (into folder Plugins)
On each part, i also tried:
"Reimport All"
Closing and opening back Unity Hub then Unity
I found nothing much on google except for having this problem only on Visual Studio (which is not my actually problem since Unity itself doesn't accept UniRx)
But those who have that problem, i read that you need to "Assets" -> "Open C# Project"
Can anyone help me with my problem on Unity ? Searched for hours but still stuck :(

The error is pretty straight forward.
Can you reinstall it with maybe the av off (or add an exception to the av).
You could also try a different version 2020.3.something else and see if it works.
Also check if you have proper read/write folder attributes where the unity files installs.

Unity 2020.1.10f1 Package Manager Won't Open

I was working on one of my projects and meanwhile, I wanted to download a package and I noticed that the Package Manager would not open. I read forums written to have the com.unity.package-manager-ui in the manifest.json file, I didn't have it. Once I put it in, I became aware of 600 error messages. Then I checked your official unity project on GitHub but there was no package-manager there either. I reinstalled Unity and Unity Hub, but it still didn't open and my manifest file didn't include package-manager-ui either. If anyone could help solve the problem I would be very grateful!

Unity 3D is Layout Errors On a fresh install

Unity 3d doesnt work, when I try to open my project it says that This can happen if layout contains custom windows and there are compile errors in the project. I tried reinstalling OpenGL and something that I found on the internet but didn't work. The error window says that Revert Factory Settings but same thing happens after it too my Unity version is 2020.1.0a My OS is Ubuntu and I gave all the permissions to some folders. Didn't work And all this happened after a fresh install
Unity 2020.1.0a3 is an ALPHA VERSION!
As any alpha version it is not stable for production and can be expected to be full of bugs and unexpected behavior.
Search through the Known Issues in 2020.1.0a3 maybe your problem is already listed there.
In general do not touch alpha or beta versions unless you want to checkout a new added feature and test it.
For anything else stick to the stable releases like 2019.1.14f1 or 2019.2.6f1
On the last letter you can see their state:
a = Alpha
b = Beta
f = Release
Not sure if these are related but here and here also others had this problem already in early version so maybe one of their hot-fixes work for you as well.
This error may occur in released versions.
To resolve this problem:
Go to this directory:
C:\Users{YOUR_USER}\AppData\Roaming\Unity\Editor-5.x\Preferences\Layouts\default
Open Default.wlt file with Notepad or any text editor and copy all its contents.
Go to your unity project directory like this:
{YOUR_UNITY_PROJECT}\Library
Open CurrentLayout-default.dwlt file with Notepad or any text editor and delete all its contents then paste the contents of Default.wlt that you copied in step 2
If these files exist in Library delete them:
CurrentMaximizeLayout.dwlt
CurrentLayout.dwlt
Stop the Unity Hub service by a click the system tray and right-click on Unity Hub icon then select Quit Unity Hub.
Run your project again.

Getting "Error: Failed to connect to OmniSharp"

I'm trying to get VSCode working with my Unity projects, and every time I select the Project icon (the little fire at the bottom) I get the following error:
Error: Failed to connect to OmniSharp
Is anyone else getting this?
You need to download the most recent version of "mono". Open up terminal and pass in brew install mono. Then "Pick a project" and select the ..-csharp.sln file and you should be up and running.
Ok, made some progress and gotten a few Unity projects working. It seems that you need some prerequisites installed, a clean up of your Unity project folder, and possibly some hand editing of your .sln and .csproj files.
I posted a (possibly) better answer over on Reddit. Hope that's not breaking stack etiquitte.

i get this on windows when my project directory has a space in it
i removed the space and removed the error
i expect it will be fixed soom
I have a completely different answer: it's the runtime that VSCode is using. It doesn't match up with what it thinks it needs. I have to remember that we're still in beta and that things are changing rapidly. I had my dnvm running beta 7, but VSCode (and OmniSharp, by extension) is looking for beta 6, so it was failing. I updated my runtime using this this post as a clue. Now I have VSCode 0.7.0 using the beta 6 runtime. I have no idea how to tell what it's looking for...I just guessed based on when they were both released. HTH
