[PySide] Problem promoting a custom widget in QtDesigner

[Friedemann Kleint]

Hi,

this means QUiLoader cannot find/load the C++ plugin with the Python 
custom widget. You don't want this machinery in your application though; 
please use pyside6-uic

as described in "Option A: Generating a Python class" 
https://doc.qt.io/qtforpython-6/tutorials/basictutorial/uifiles.html .

Regards, Friedemann
