Unity Editor Crash

[avolkangursel]

What happened?

I occasionally encounter an error in the Unity editor. It crashes and closes the editor.

Repro steps

I'm not exactly sure how to reproduce it consistently. It might be related to AssemblyReload when code changes during runtime. I'm not sure.

Version

11.0.0

What Atlas Services are you using?

What type of application is this?

Unity

Client OS and version

MacOS 13.0.1

This appears to be a race condition when using GetInstanceAsync and reloading the domain. Don't have the full picture yet, but it appears to be caused by the async open callback firing after we have cleared the native caches due to the domain unloading. Right now I don't see an easy way to avoid it, but will try and come up with a repro case and hopefully a workaround.
