thanks @nobodyinperson! I'll have a look at it ASAP, but I need to test this on my private Mac 😅 The error message does not really help and I strongly assume it's something related to PyQt5. Can you try to open other PyQT5-based Applications? E.g. spyder?

I packaged psyplot and psyplot-gui into the AUR.

What is AUR? (My apologies if this is a stupid question)
