Python 3.12 + django 4.2: debug doesn't work

[senseysensor]

Not sure what is the root cause of the issue, pytest debug in Python 3.11 works fine.

So I try to run the test as usual in debug mode via PyCharm, but get error django.core.exceptions.ImproperlyConfigured. Even if I supply DJANGO_SETTINGS_MODULE env variable manually, I get next errors and I guess it is wrong direction for fixing the issue.

Same problem, same packages!

[PavelPancocha]

Exactly the same stacktrace!

[exister]

Had the same problem, turns out it is caused by pycharm https://youtrack.jetbrains.com/issue/PY-65169/Django-debugger-breaks-with-low-impact-monitoring-api-enabled

[PavelPancocha]

@exister That works! Up-voted that PyCharm bug report. Thank you!
