The release notes suggest (on newly installed systems) installing python-is-python3 package for a /usr/bin/python pointing to python3 instead. It still doesn't fix the problem, I think it has to be Gimp specific python. I'm using the Appimage, it is integrated so it still appears on the menu/app list and I can still add assets.
