      When running Pyside6.5.0 on python 3.10, 3.9 and 3.8 the application gives the error: 'qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
      This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

      Available platform plugins are: wayland, wayland-egl, minimal, minimalegl, vkkhrdisplay, eglfs, vnc, xcb, offscreen, linuxfb.'. To resolve I had to downgrade to PySide 6.4.3.

      Another college friend had the same problem.
