4. Change 'MyScript.cs' to trigger a Domain Reload
5. Observe the Unity Console Window
Expected result: No errors are thrown
Actual result: A "Missing Prefab Asset" error is thrown
Reproducible with: 1.1.0-exp.1 (2022.3.40f1, 2022.3.42f1), 1.3.0-pre.4 (2022.3.40f1, 2022.3.42f1)
Not reproducible with: 1.3.0-pre.4 (2022.3.39f1, 6000.0.14f1)
Unable to test: 0.51.1-preview.21 (2021.3.42f1) (Unresolvable package problems due to downgrading)
Reproducible on: Windows 10 (user), Windows 11 pro
Not reproducible on: No other environment tested

Yay, fix in review. I guess two more months and this showstopper will finally get into release build of Unity.

Unacceptable that this was released and is still an issue. Lost a whole day trying to debug this nonsense. WTF

I am pretty sure that another related issue was introduced in 2022.3.40: https://issuetracker.unity3d.com/issues/materialmeshinfo-does-not-point-to-a-valid-mesh-error-for-runtime-created-entity-when-using-mesh-slash-material-indices-for-multiple-meshes-slash-materials
And they all are realted to this fix: https://issuetracker.unity3d.com/issues/job-allocator-contention-causes-slow-job-execution
