The exact error is: During initialization the error "No module named 'PySide2'" occurred in /home/noah/.local/share/FreeCAD/Mod/A2plus/./InitGui.py .
Is there a way to do it without PySide2? I've tried looking into the files and found that the one that requires it is automatically generated, and I can't find documentation on how to generate it (I'm not familiar with rcc).
