What you're telling me is very disturbing. To paraphrase, the actual Windows attributes which control file access privileges are not displayed by "ls" and cannot be changed by "chmod".
That being the case, ordinary software development becomes difficult. My software development is shared between three Windows users. I often have to use Cygwin or Windows File Explorer to fix access problems. I will probably abandon MSYS2, and go back to using Cygwin and WSL/Ubuntu. Richard H.
