Additional information
I'm facing two failures on stestr.tests.test_return_codes.TestReturnCodesToxIni.test_no_repo_dir and stestr.tests.test_return_codes.TestReturnCodesToxIni.test_empty_repo_dir. And it seems that the same error happens in both tests.

This issue doesn't happen on python 3.11.8 on my environment(Fedora39) somehow.

$ python --version
Python 3.11.8
$ stestr --version
stestr 4.0.1.dev14
$ stestr failing
PASSED (id=13)

Looking at the code, the tests fail when running stestr run passing after shutil.rmtree(stestr_repodir). I'm not sure why this failure happens only on python 3.12 yet..

https://github.com/mtreinish/stestr/blob/main/stestr/tests/test_return_codes.py#L229-L240

    def test_no_repo_dir(self):
        stestr_repo_dir = os.path.join(self.directory, ".stestr")
        shutil.rmtree(stestr_repo_dir, ignore_errors=True)
        # We can use stestr run even if there's no repo directory.
        self.assertRunExit("stestr run passing", 0)

    def test_empty_repo_dir(self):
        stestr_repo_dir = os.path.join(self.directory, ".stestr")
        shutil.rmtree(stestr_repo_dir, ignore_errors=True)
        os.mkdir(stestr_repo_dir)
        # We can initialize an empty repo directory.
        self.assertRunExit("stestr run passing", 0)

On Arch Linux with 3.12 we get:
