-- Information about the crash:
Travaillant depuis mon ordinateur portable, j'ai branché un 2e écran et, au moment d'appuyer sur le bouton d'allumage de l'écran, le gestionnaire de bureau plasma a planté, pour se redémarrer de manière automatisée.

The reporter is unsure if this crash is reproducible.

Working from my laptop, I plugged in a 2nd screen and, when I pressed the screen power button, the plasma desktop manager crashed, only to restart automatically.

Thank you for the bug report. I'm not able to reproduce this on git-master. Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong:

#9  0x00007f89b6fe4443 in ??? () at /lib/x86_64-linux-gnu/libQt6Core.so.6

Could you please install debug symbols and 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!

The backtrace as it is looks similar, but not identical to bug 499383

This looks like a duplicate of bug 499383, which has been fixed with Plasma 6.3.4 with Frameworks 6.13
Once your system has gotten these updates, this crash should stop happening
