Qt causes Python's Py_Main to no-op on Windows

There is a a very weird bug with Python 3.10.4 and Qt such that if you reference any non-trivial Qt classes or methods (such as qIsFinite, QString, or QVector) on Windows, trying to call Py_Main (or Py_BytesMain), which runs the standard Python interpreter's main function, will result in a no-op (the program will immediately exit 0 and not show the Python interactive shell). Furthermore, the bug is absent on MacOS, and the bug occurs with both MSVC and MinGW builds of Qt. I have linked a minimal example of the bug at https://github.com/Landmaster/python-embed-qt-bug The corresponding bug report on the Python side is at https://github.com/python/cpython/issues/93013
