this just doesn't work on python 3.9.
This script stalls and gives no errors.

I tried on Python3.9.13, pyside2-5.15.2.1, shiboken2-5.15.2.1 and Windows10
It works well.

So could you give me some more information? What happens if you try "python input_dialog_example.py" on command prompt?

I suppose it has to do something with my system, can't get it to work on my mac 12.3.1 (monterey).
It shows a blank window and after a while i'm getting a python crash, this exact code runs fine with PySide6 or pyQt.
