How to repair a broken Package Manager

Questions & Answers

Hello,
I’ve downloaded an older project from the cloud now that I’ve got time to actually do something about it.

But when I opened the project some rather mysterious exceptions popped up in the log:

Assets/Scripts/MoveCam.cs(86,3): error CS1070: The type ‘UnityEngine.RaycastHit’ has been forwarded to an assembly that is not referenced. Enable the built in package ‘Physics’ in the Package Manager window to fix this error.

Assets/Scripts/MoveCam.cs(89,7): error CS1070: The type ‘UnityEngine.Physics’ has been forwarded to an assembly that is not referenced. Enable the built in package ‘Physics’ in the Package Manager window to fix this error.

Now I figured I could fix this in the Package Manager… But it’s just a grey screen. I get following log warning though:

Style sheet not found for path “Packages/com.unity.package-manager-ui/Editor/Resources/Styles/Main_Light.uss”
UnityEngine.GUIUtility:ProcessEvent(Int32,IntPtr)

Does anyone have an idea what I can do to fix this issue?

Maybe some one more experienced could give you better advice here but I hope you made a backup cause that sounds like a error having to do with upgrading a project from an old unity version to a newer one. I would say create a new project with the newest unity version and copy over your assets folder.
