Pyside6 in Ubuntu20 does not work suddenly

[Jakkwj]

Hello.
I used pyside6 under ubuntu 20, it used to work fine.
But I find pyside6 stop working in these few days.
It just do no show any window not matter what, enen if I ran a super simple python code ('hello world' window)
and no hint at all in the terminal...

I think this may be some library missed? How could I fixed this? Or do I have to reinstall ubuntu 20?

Hi and welcome to devnet,

How did you install PySide6 ?
What do you get if your set the QT_DEBUG_PLUGINS environment variable to 1 before starting your script ?

Hi~
Thanks you!

I turn QT_DEBUG_PLUGINS on, and it seems my python env mess up (system, anaconda and pyenv env together)
So after I delete anaconda and reinstall pyenv to clear the env varialbe, everything worked again~
