New description:
The `iter_modules_and_files` function from `django.utils.autoreload`
raises `TypeError: unhashable type: 'types.SimpleNamespace'` when a
`types.SimpleNamespace` is put into `sys.modules`.
This is for instance the case when the `zipp>=3.18.2` package is used (see
[https://github.com/jaraco/zipp/blob/d66007a66b7dbd88e69eaf59faae8b614cba256d/zipp/compat/overlay.py#L23])
which is used by `importlib_meta>=8.5.0` (see
[https://github.com/python/importlib_metadata/blob/90073b1aa7a49cc5fdbdc0e6e871f39e461b9422/pyproject.toml#L21])
The error can be reproduced by putting `from zipp.compat.overlay import
zipfile` somewhere in your django project.
