Unity cannot recognize some .cs files after pulling a project from git

Question

I am currently developing a project using Unity 2020.3.3f1. I use git version control system and store my project in a Bitbucket repository. When I clone / pull my project to another computer (especially with macos) some of my cs. files are displayed as an unknown file` (not a script) in the project view, and some other classes cannot find the class defined on that file. When I right click and select "reimport" the cs file, recovered immediately and I build successfully.

This causes me a problem when I try to build my project through Unity Cloud build, because I get an error about some missing classes which are indeed there.

After that I tried pulling the project from a Mac device, the project also could not recognize the same MaterialLayer.cs. I easily recovered using "reimport". My project settings / Asset Serialization : Force Text and "Version Control / Visible Meta Files" are already set.

It's a long shot and I write answer only because I can attach image here:

Every file in C# solution has properties:

So my suggestion is to double check if those "missing", "unknown" .cs files have same properties set as those .cs files, which are recoginzed correctly.

If you using LFS on git then this issue sometimes happens when LFS pulled with a bug or metafiles was broken during pulling files, please double check your .gitattributes. It's possible that the merge option for .meta was wrongly assigned. I'm using this .gitattributes for my projects, still no issues with this.
