Why is Git acting so weird?

Question

git

The issue is Gita's strange behavior. So the situation is:
Until now I have been using Git as part of cygwin. All work on all projects where it was used was committed.
Now, for some reason, I had to abandon cygwin, and I installed git fully, into the operating system, as an application. And now, having entered the directory with any of the projects, where, I repeat, everything is committed, the git status command gives me the entire set of project files, as if this is the first commit. There is a .git folder, git log works, that is, all the commits made are displayed. Why does git status work so strangely, why does it offer to commit all files again? Git is already initialized, and there is the whole story .... Why is that?
