Comment 1 TraceyC 2025-02-12 20:10:57 UTC 
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:

#13 0x00007839dfd7db20 in ?? () from /usr/lib/qt6/plugins/plasma/kcms/systemsettings_qwidgets/kcm_kgamma.so

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!
