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.
