Max 2023 crashes after importing PySide2.QtMultimedia or QtMultimediaWidgets

Tested Environment:

  • 3ds Max 2023.3.4 Security Fix
  • PySide2 5.15.2.1 (latest version in pypi.org)

How to reproduce:

  • Run `from PySide2 import QtMultimedia, QtMultimediaWidgets` in Scripting Listener -> Hover mouse to "Play Animation" button -> UI goes no response and crashes soon.
  • Hover mouse to "Play Animation" button -> Run `from PySide2 import QtMultimedia, QtMultimediaWidgets` in Scripting Listener -> No crash / No problem with UI.

Note:

  • Downgrading PySide2 to the factory version(5.15.1) of 3dsMax installation fixed the problem. However, stdout was broken(i.e., print() never prints anything in Scripting Listener) if I downloaded 5.15.1 from pypi.org, by `pip install PySide2==5.15.1`, rather than using the factory version.
