Strange import behaviour with Python 3.12.3 during debugging

[ArVar]

Apperently something has changen with how imports are processed in python when debugging.
In datamodel.py the import function iterates throgh all key-value-pairs of the variables in frequency.py on import (!).
This leads to an incredible long import time when running in debugger. (VSCode Python Debugger)

I've checked the changelog for python 3.12.x and a lot of other ressources and did not find any hint. Maybe replacing import with importlib.import_module can help.

Has anyone else a similar issue?

I think, this is adressed here as well: microsoft/debugpy#1496

looks like it was fixed upstream python/cpython#119118
