-- Information about the crash:
I was using Plasma/KDE normally. I had several Vivaldi windows open, as well as
ChatGPT, and was switching between the different windows and Konsole.
Then, all of a sudden, the entire desktop crashed during normal use.
Vivaldi does crash occasionally, but having the entire desktop crash is much
less common.
The crash can be reproduced sometimes.
-- Backtrace (Reduced):
