A lot of QTWidgets related errors and GUI mostly unusable

Description:

I get a bunch of QTWidgets related error messages as well as most of FreeCAD is unusable. E.G. Trying to create a new Path Job. (Open one of the examples. Select "Path" from the dropdown at the top and then click the "Create Path Job" button.

Additional info:

• package version(s): 0.21.2-13
• config and/or log files:

During initialization the error "'PySide6.QtWidgets.QStatusBar.removeWidget' called with wrong argument types:
  PySide6.QtWidgets.QStatusBar.removeWidget(QPushButton)
Supported signatures:
  PySide6.QtWidgets.QStatusBar.removeWidget(PySide6.QtWidgets.QWidget)" occurred in /usr/lib/freecad/Mod/Tux/InitGui.py
Please look into the log file for further information

• link to upstream bug report, if any:
• May relate to #3 (closed)
• Similarly to #3 (closed) downgrading to 0.21.2-6 ( f1567c38) resolves these issues and is currently the only way for me to have a usable FreeCAD:

  $ sudo pacman -U https://archive.archlinux.org/packages/f/freecad/freecad-0.21.2-6-x86_64.pkg.tar.zst

Steps to reproduce:

1. Open FreeCAD
2. The left most example project
3. Select a workbench e.g. "Path" and click the "Create Path Job" button.
