-- Information about the crash:
After unlocking from the lock screen, KWin crashed and together with it all the XWayland applications.
Everything else recovered almost immediately but I got another crash regarding powerdevil one second later. Unsure if they are related.

Thanks for the bug report.

This looks like the same backtrace as bug 511438. That was marked a duplicate of bug 495702, which had a fix merged to Plasma 6.5.1. This crash should stop happening on your system when it updates to that version.

If you still see the crash after updating to Plasma 6.5.1, feel free to reopen this report. Thanks!

I'm now on Plasma 6.5.3 and it never happened in the last few days.
Thanks again.
