Question by Ramedlow · Mar 08, 2021 at 04:08 PM · c#unityeditor error message console

ForcedScopedThreadAttach

Unity 2020.2.6f1 throws an error (in the Editor Console) while running my C# project:

ForcedScopedThreadAttach can only be used from threads that are not already attached.

There is no stack trace for it. If anyone has encountered such an error or has an idea what I am dealing with, how can I find out the origin?

I got the same with Unity 2019.4.18f1 and 2019.4.21f1 on macOS. It seems it has no side effects on the application. I have the suspicion it has to do with the async/await stuff that I started using. The error appears quite erratic but regularly. As far as I can tell it happens only when I run the project in the Unity editor.
