Reproduction steps:

Not reproducible with: 2021.3.21f1, 2022.1.0a5
Couldn’t test with: 2020.3.46f1 - Scripts in assets do not compile, 2022.1.0a6-2022.1.0a8 - The Editor crashes

Reproducible on: Windows 10

  1. Resolution Note:

    Future releases of Unity with Core CLR support should address this bug. Meantime I realize that many users are on older versions of Unity and that's not available yet - in the meantime, if you have Unity Editor performance issues I'd suggest following the suggestions in this document to help improve your Editor performance: http://blog.s-schoener.com/2023-08-16-why-your-unity-project-is-slow/
