Some time ago (and several system updates later, including updates to Calibre) Calibre starting failing to load (crashing?) after the splash screen.
I start Calibre -> The splash screen appears and shows the usual loading. -> The splash screen disappears. -> Calibre does not load. There are no errors. No tray icon. Just nothing.
I'm on Arch Linux with Deepin DE (system is up to date including Calibre).
I tried running Calibre in debug mode (calibre-debug) to no avail. After some hunting I found this command
Code:
calibre-debug -c "from calibre.gui2.main import main; import os, sys; os.fork() != 0 and sys.exit(0); os.setsid(); main()"
from
https://bugs.launchpad.net/calibre/+...00/comments/26 (Main thread here:
https://bugs.launchpad.net/calibre/+bug/1360200 )
That got Calibre to run. Splash screen appeared followed by Calibre loading. I will be honest and say that I have no idea what that command actually does. I used it as a Hail Mary as I couldn't find anything else and nothing else I tried was working.
However, since running it, Calibre seems to have blitzed my custom columns, preferences, etc. Like Calibre has reset to default but my library is still there. Maybe that command runs Calibre in a 'default mode'?
Here's the terminal output when running Caibre with that command:

Continuing on, I search these forums and found this thread which have me the idea of turning the splash screen off.

I used the above command to start Calibre then when into the Preferences and disabled the splash. Then I tried to start Calibre like normal (i.e. how I used to before it stopped working). It still will not load, however now it comes up with an "ERROR:Startup error" box with the following:
Code:

I have tried uninstalling and reinstalling and double checked the dependencies.
Clearly, something that was updated has caused issues but I have no idea what and I am out of ideas for fixing this myself. Help much appreciated and thanks in advance!
