Created attachment 168195 [details] New crash information added by DrKonqi DrKonqi auto-attaching complete backtrace.
This is most probably not a bug, systemsettings has just not been rebuilt yet for qt 6.7 (which is in extra-testing)
Can reproduce on Git Master compiled against qt 6.7. The issue only appears if you don't have a firewall installed. When opening the firewall kcm, one CPU core seems to go into a loop with 100% usage (/usr/bin/systemsettings kcm_networkmanagment in htop shows 100%). Switching the tab or exiting systemsettings crashes with the above backtrace.
