Comment 1 Nate Graham 2023-01-06 21:03:14 UTC 
Thank you for the bug report! Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong:

> #5  0x00007fe8ff8c27f6 in  () at /usr/lib64/libkwin.so.5
> #6  0x00007fe8ff8c2ef3 in  () at /usr/lib64/libkwin.so.5

Could you please install debug symbols, reproduce the crash, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Thanks again!
