Try closing the project, deleting the library folder, and re-opening the project
In Android build I found issue about gradle error when upgrade to lastest Unity.
Will try to remove library that Gambit-MSpilitz said.
I’ve done the first one… but it does this to all my projects… even when i make a new one.
(I’m building PC only)
Here’s another one I’m getting:
NullReferenceException: Object reference not set to an instance of an object
UnityEditor.GridPaintingState.UnregisterPainterInterest (UnityEngine.Object painter) (at C:/buildslave/unity/build/Modules/TilemapEditor/Editor/Managed/Grid/GridPaintingState.cs:197)

If you’re getting errors on blank projects, maybe there is something wrong with your Unity install itself or your OS?
I just barely started two new projects… AGAIN!!! And it gave me these errors AGAIN!!!
(Unity 2D)

That’s what I’m thinking…
What version of Unity do you used?
OK it might sounds super weird and i dont know why it happened but i fixed this issue. A couple of days ago my storage went full and i checked my files when i realized unity already took 40…but not from the local folder but in a hidden one, called app_data…i didnt really have nothing to lose so i deleted all my files, i thought i will reinstall unity later i fixed my pc. but i didnt have to uninstall, even with this 40gb lost, everything seems working fine…
so now i get this problem as yours and i just deleted everything from the app_data, unity subfolder.
well…fingers crossed it stays
I keep getting a similar error, using different Unity versions and working of different computers. I’ve copied the message I get bellow. The Animator window will not show any graphics because of this. Reseting Unity everytime I need to use the Animator window is really anoyng. Hoping someone will come up with a fix.

I am getting the same error. It started when working on the animator. Help please
i get the same error. I Think that the error is a unity itself error not a script coded by us also it bug my animations and teleport them in another place like the hand animation when it pay it teleport to the sky and i see in preview and the animation work fine.
(I NEED HELP)
I find the resolution in this post.
Seem to be it isn’t an error by your code. it is from modules of unity editor.
I try to restart my project like this post recommends and it is clear. Good luck guys.
thnx it worked although took long to load
