Note the issue is persistent even after clearing caches and several complete editor re installs.

Just recently had this issue on windows 10. ReadonlyMaterialConverterTests.MaterialReferenceChanger.cs has no meta file, but it's in an immutable folder. The asset will be ignored.
I checked. The metafile is definitely there, right with the .cs file.

Resolution Note:
This is a bug in the com.lupidan.apple-signin-unit package that must be fixed by the package owner by ensuring that the .meta files are in the package and the package.json file lists all the package files. As a work around the package can be embedded into the project which makes it possible for the asset database to add the missings .meta files which it cannot do when the package is in its default immutable location.
