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

This issue is blocking our development as well. Could this be prioritized for a fix? Thank you.

This makes all editor versions >= 2022.3.40f1 completely unusable for entities development. Fix needed ASAP. Should never have been released...

This issue is also entirely stopping our current development.
This occurs when a prefab either in the subscene's hierarchy or a prefab referenced in a baker in a subscene has any kind of MonoBehevior component (URPMaterialPropertyBaseColor or any other Authoring for example).

Why this is not instantly fixed? UNITY IS NOT USABLE BECAUSE OF THIS.

The same here.. After more debugging, it turned out that this issue occurs when you have Baker script on your prefab object. Without baker script it's working properly.
