Django Server stuck after updating from python 3.9 to python 3.10 (using Django 4.1.5)

Question

After upgrading python 3.9 to 3.10 the Django Server isn't working locally anymore (I'm using the Django Server Plugin for Pycharm). In my gitlab pipeline it seems to work allright.

Below you can see further details (click link to see screenshot):

With a Python 3.9 venv some errors occur, but the Django Server works nevertheless

With a Python 3.10 venv the same errors occur, but the Django Server doesn't start (after waiting 30 min)

(Working on linux and with pycharm)

I have the same requirements installed on both venv s except for the python version. I'd expect an error message, but it seems the execution is just stuck.
