Hi there With the update to KDE Frameworks 5.39 we seem to have caught a bug.
systemsettings5 will segfault if you enabled the new kirigami2 based view. If it crashes you can edit ~/.config/systemsettingsrc by setting 'ActiveView=icon_mode' in the Main section: === [Main] ActiveView=icon_mode === or adding if if it is not present. mfg Tobias
