Thank you for this report, I am sorry for the trouble! Are you by any chance on Arch, running from source? They just updated to python 3.8, which as luck would have it PySide2's C++ wrapper, Shiboken, doesn't work on! Fuck! Word is they are scrambling to fix it all, but who knows when that will be done.

There are new details in the running from source doc here:

Basically, you'll be removing PySide2 and using PyQt5 instead. If you can't remove PySide2, you'll have to start hydrus with an environment variable QT_API=PyQt5.
