Thank you for asking @matt. This time it's Fedora 31->32, last time it was Pop!_OS 19.04->19.10.
I don't know what I'm doing to myself between versions but each time I upgrade a distro I find major bugs in stuff I didn't expect.
On top of Gnome crashing, Docker has networking problems (resolved) and Pulseaudio isn't behaving (ongoing but might be related to the Docker issues).
