The issue seems to be in libgit2 libgit2/libgit2#6049 where the is_empty function only returns true if the branch is called "master". This causes the issue in this line where is_empty is set to false for empty repositories with a "main" branch instead of "master".
The fix is pretty simple, just need to try and get the head, if we can't get the head the repo is empty, otherwise, it is not.

I'd be happy to submit a pull request for this as well if you prefer.
