I thought it should be something outside apps… but Idk what could it be
If you don’t have any of your apps listed in the INSTALLED_APPS setting, then the next thing to check would be version compatibility among your third-party apps. Please post the output from a pip list command.

There are no versions of Django 4.1 listed as being compatible with Python 3.12. I suggest you install Python 3.11. See FAQ: Installation | Django documentation | Django
Thank you very much for your help!
I still cannot resolve my situation. But now I understand that the reason is somewhere there)))
I have installed python 3.10, 11 and 12 on my local machine and try various combinations with versions of django. Sometimes python manage.py check shows me ‘Apps are not ready’ and sometimes ‘Models…’
And now after all previously locally working combination of python 3.10 and django 4.1.6 isn’t working now(((
Why is it so hard? How to avoid those problem in general?
If you’ve got a previous combination that works, then I’d go back to that and start working forward incrementally.
Also, for each addition and update, you may want to look at the packages individually to see what versions of Python and Django are supported by it.
Because there are about three dozen different packages you’ve got listed here, each with their own constraints, requirements, and interactions.
Don’t try to do too much at once. When you’re going through an upgrade cycle, don’t mix that with any other code updates.
