Description (last modified by Paul Petersik)

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.

This problem was already discussed and analyzed on stackoverflow:
