The pkgutil.iter_modules crash when using Path object in the first argument. The code below works in python 3.8.9 and 3.9.4, but stopped working in python 3.8.10 and 3.9.5. Changing from Path to str works in all versions.

import pkgutil
from pathlib import Path

for _, modname, ispkg in pkgutil.iter_modules([Path("/home")], 'somepackage.somesubpackage'):
        print(modname, ispkg)

Error message from python 3.8.10 (other path was used):

Traceback (most recent call last):
  File "/home/devel/Python-3.8.10/Lib/", line 415, in get_importer
    importer = sys.path_importer_cache[path_item]
KeyError: PosixPath('/home/devel/pharmpy/src/pharmpy/plugins')

During handling of the above exception, another exception occurred:

  File "", line 5, in <module>
