I am not sure how to reproduce it but it happens randomly, sometime when i open application or sometime when I am testing Proton Game and i close reopen multiple time and it causes hangup whole computer, Before DE stop responding then everything else crashes and have to restart Forcefully

Provided log for the boot that had crash/hang

OBSERVED RESULT
Sometime opening application causes hang

EXPECTED RESULT
If there is a crash or any error, DE should recover from it.

Can you capture dmesg logs too?

Am not sure how to get dmesg for last boot, ```journalctl -b -1 -k ```

And dmesg logs, not sure how to fetch dmesg log for last session.

It was related to my Samsung 980 Pro, I updated the firmware and it fixed this issue, so far no crashes.
