PySide6 on Linux for desktop app with GUI not work

Hello all, i’m new of this forum and also on Python developing but i like very much.

I use Linux Kubuntu 25.10 and PyCharm and i am intented to develop multi platform desktop gui app… for example a reminder for start…

I follow many instruction for import PySide6, i activate VENV in my project and all suggestion readed, but pycharm mark on red every PySide import command…

Someone tell me is for incompatibility on Python 3.13, but i cannot trust could be for this…

Colud you guide me to configure my system and PyCharm to be full functional with PySide6 ?

In my past, i used PyQT5 with python on a Windows machine, without problem…

Thanks!
