This crash happened after (or while) the system went to sleeep after inactivity.

The crash can be reproduced sometimes.

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:

Could you please attach a new symbolicated backtrace generated by using `coredumpctl gdb` in a terminal window? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl for details about how to do this.

Thanks again!

Hi!

Thank you for reflecting on it. My problem is that installing the debug
symbols using the button in KCrash doesn't work... Is there a way to
manually install these?

Thank you,
Attila

Yep, follow the instructions I linked to.

Also if you reply to bugzilla emails, please remove all quoted text, as otherwise it's very distracting on the website.
