There is a similar bug: #550

This problem also occurs on windows when calling a module entry point (executable) instead of directly calling the python interpreter

I am seeing this on a bunch of module entry point executables on Python 3.10 on Windows, as above. Austin does manage to do it, so I assume it's possible.

Be aware --subprocesses may help if you're using a venv, but doesn't help with 3.10+

@gobater I assume you meant to link to this similar bug: #498?
