I am running Calibre 5.7.2 in Ubuntu 20.10.

In order to diagnose a problem with the DeDRM plugin I have tried, multiple times, to reboot in debug mode, both from the menu and by using Shift+Ctl+R. Each time, the program hangs. Nothing is clickable and when I minimize the window I see the box that reads "Starting up, please wait...Initializing user interface".

I end up having to kill the process.

Anyone else experiencing this? Any ideas?

UPDATE:
After killing the process, I do get this log, which doesn't seem to me to shed any light:
