Try exiting and restarting Unity.

This is an error in Unity’s code, which is located in UnityEditor.Graphs.DLL. The C: in the error message refers to the Unity developer’s environment when that DLL was built, not your computer. Judging from older forum posts and unityAnswers, it seems to occur most frequently when deleting and recreating animator controllers that don’t have any transitions.

If the error persists, you can upgrade Unity or report it as a bug.

@TonyLi this seems like a pretty likely scenario given the location of the error. Good advice.

Glad it’s working again. I primarily develop on Windows, so “when in doubt, restart!” :slight_smile:

Thank you, @TonyLi .
Restating Unity worked for me

@TonyLi worked out for me too! :slight_smile:
Thanks a lot!

It is Causing Unity to crash and corrupting my scene and I cannot open that scene again, it permanently crashes unity. I have removed Unity 100% and even cleaned the register and reinstalled it to no avail.

@howler123 uh-oh, I just pushed my commit to github with this error, I had a lot of big changes between now and the last commit :face_with_spiral_eyes:
EDIT: Restarted and that error is gone, works fine. PHEW!

Just encountered this one. A restart seems to have fixed it. I was creating animation clips (for a camera) in timeline, then popping those in an animator. On the camera. Which was also still referenced in the timeline.

I don’t think they care much to fix it. 2019.4.2f1 LTS here and still around.

2020 and the problem persists. Please do not tell me to restart unity. That works for about 20 minutes before the problem reappears.
