Unity hangs when opening project in Visual Studio

Unity gets stuck loading with something like these messages when I try to open the project in VS.

ProjectBrowser.MouseDown

Waiting for Unity's code in UnityEditor.CoreModule.dll to finish executing

or

MenuItem.Open C# Project

Waiting for user code in mscorlib.dll to finish executing

I'm forced to kill Unity, but when I restart, VS opens without issues. But then next time I run Unity it hangs again.

Unity 2021.2.8f1, Visual Studio 2022.17.0.5
Did not have this issue in Unity 2020.

Troubleshooting is slow because of all the hangs and restarts so I appreciate any help I can get.

 

The same problem here, cant open a project I worked in yesterday, using Unity 2021.2.16f1

Help

 

The problem was Plastic SCM without internet connection, check it here

https://www.reddit.com/r/Unity2D/comments/sjttim/stuck_on_projectbrowserrepaint_infinitely_when/

I solved it by installing the Plastic SCM Cloud Edition and log in in the application, then I could open the project normally.
Sure it has to be fixed

 

I solved the problem by going to the directory in File Explorer for my project, I did a local search for the keyword plastic, and everything that popped up I simply sent to the recycle bin to be deleted. Project opened right up, and I'm going to immediately remove the "Source Control" package from my project! Thanks for the pointers!

 

Hmm, started getting this problem now, i have not updated or anything but now all of the sudden..
Running on 2021.2.18f1.

Edit, now opened same project in 2021.3.0f1,,
same issue..

Eventually it times out after 5 ish minuttes and crashed the editor..
Running visual studio on it's own works fine, but with unity,, not anymore.

 

Solved this by starting the Plastic SCM client before opening the Unity project

 

Try - Go to Plastic SCM Dashboard> Cloud> Configure> Network allow list> add your IP to the list then Save.

 

This is the same problem in my case . it worked . Thanks

 

did you have to pay? Im paying unity 5$ a month to use their GIT system....

 

That works!

 

After running into this yet again and having tried all the solutions before, I have found something that nobody else has mentioned, as far as I can tell, and it solved my problem. Note this occurred on 2021.3.3f1, but I'd bet quite a lot that it will solve the issue on other versions as well.

It's Windows' file and folder security.

Opening and then modifying the Windows Security Settings on the Project folder so that Users can have Full Control instantly solved it. After uninstalling and then reinstalling the package Visual Studio Editor to regenerate the csproj after that (as I ran into an issue where the sln and csproj weren't generated at all), I can open VS easily from Unity. Assets > Open C# Project, Edit Script in the Inspector, and double clicking both from the Project Browser and the Console log work.

 

This fixed the problem for me as well, praisebe.

I duplicated an older project to make a new project and it was just hanging on open.

 

Just want to add my +1 to this problem, I'm getting it constantly in 2021.3.5f1, including this guy:



This time it's because I tried to *close* the editor :|

 

issue recently started again, and NOT using plastic..

 

Confirmed, just starting happening to me

 

Try restarting PC, seemed to fixed the issue for me.

 

Been facing this issue after creating a script, it got severe to the point clicking on a gameobject would trigger this, removed plastic SCM gonna try to restart
although worth mentioning that I started facing this after I added entities package, but I think this goes beyond entities

 

this may be related with the issues from this thread. but don't get your expectations high. there is no solution

Just want to add that I have the same problem.

 

same issue here

 

why is this still happening?

 

still happening

 

What even is plastic SCM and how do I fix this issue?
