Sudden compile error with text mesh?

[Marscaleb]

I was working on an animation and suddenly I have this massive compile error.

InvalidOperationException: Stack empty.

It is followed by another eight similar errors. I can’t run any test plays with my game, and I never edited ANY code here, much less anything within these packages that have been working perfectly.

This looks like a Unity wedge… close Unity and reopen.

If that doesn’t fix it, underneath your specific project (right next to Assets and ProjectSettings) there is a folder called Library/ScriptAssemblies/ and you can also try exiting Unity, deleting that folder, then opening Unity.
