As you mentioned, filenames are case insensitive on Windows, so Logging and
logging are the same thing. But if that module is inside a package (i.e.
you're doing import testcx.Logging instead of just import Logging), then it
shouldn't be directly on sys.path, so it shouldn't be found as the Logging
module.
My guess would be that because you're freezing testcx/app.py, it treats
that as a script, so it adds its containing directory (testcx/) to
sys.path, and that means that it sees Logging.py as a directly importable
module.
