I tried to test our project with Python 3.12 beta 1 on Windows but everything failed. After some debugging I noticed that module imports seem to fail when modules aren't on my C-drive:

C:\Users\peke>echo print(1) > test312.py

C:\Users\peke>py -3.12 -c "import test312"
1

C:\Users\peke>e:

E:\>echo print(1) > test312.py

E:\>py -3.12 -c "import test312"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'test312'

No problems with earlier Python versions:

E:\>py -3.11 -c "import test312"
1

Not sure does it matter, but I'm running Windows on VirtualBox and that E-drive is mapped to a directory on the Linux host.
