PySide2 is not yet compatible with Python 3.11. Indeed Ryven's version requirements currently do not account for PySide2 restrictions. It should do so in future releases.

closed in https://github.com/leon-thomm/Ryven/releases/tag/v3.5.0

you can now use Python 3.11 with PySide6<6.7 pip install 'pyside6<6.7'
