Comment 12 Shadders 2023-08-07 18:03:07 UTC 
Hi,
To add further information - issue seems to be pipewire. Searching my records the following applies :

2023 01 26 Update - pipewire 0.3.63-1.fc36 - no crash issues and same for all fc36 updates.
2023 05 15 Upgraded to F37 - pipewire 0.3.70-1 no issues. 
2023 06 03 Update - pipewire 0.3.71-2 - 1 instance of a crash.
2023 07 26 Update - pipewire 0.3.75-2 - 3 instance of a crash.
2023 07 30 Update - pipewire 0.3.76-1 - 4 instance of a crash.

Unsure if it is a stability issue between pipewire and wayland, and whether it exists between pipewire and x11. Pipewire 0.3.70-1 may have an issue as only 19 days between that version and then ext which had 1 crash for kwin. 

Regards,
Shadders.
