Every time I run a PySide2/6 app I get the following error printed in terminal:
qt.qpa.fonts: Unable to open default EUDC font: "C:\\WINDOWS\\FONTS\\EUDC.TTE"
It seems like there was a wrong registry configuration of my PC and Qt tried to find a font called EUDC.TTF font, which did not exist. https://bugreports.qt.io/browse/PYSIDE-1620
