I will try to get some, but it's hard when my system just logoff.

journal and coredumps are still available after logoff

So kwin is crashing, as expected, but the coredump is larger than 2G so it's not being saved. Try increasing ExternalSizeMax in /etc/systemd/coredump.conf, without a backtrace there's not much we (or KDE for that matter) can to about this

New journalctl and coredumpctl's backtrace. The coredump itself is about 20mb and I can't send it here.

Alright, thanks. The crash is caused by the aurorae window decoration engine. Please report it upstream and, in the meantime, switch to one of the official window decorations (breeze or oxygen)
