Thank you for the bug report! Unfortunately the backtrace is incomplete and missing debug symbols for the following that we need to figure out exactly what's going wrong. Could you please install debug symbols, reproduce the crash, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports Thanks again!

Created attachment 146473 [details] New crash information added by DrKonqi systemsettings5 (5.18.4) using Qt 5.12.8 - What I was doing when the application crashed: I was initially opening display settings from KRunner. After noticing the crash, I attempted to open Settings through the menu and it, too, crashed. - Unusual behavior I noticed: Prior to the crash, one of my three monitors went completely grey. The content underneath is still present and the monitor is still detected as a display. This is a frequent occurence (one that I remedy by disabling and enabling the affected display) and a different bug but could potentially be related to this due to the timing. -- Backtrace (Reduced): #6 __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:50 #7 0x00007f924ac09859 in __GI_abort () at abort.c:79 #8 0x00007f924b03daad in QMessageLogger::fatal(char const*, ...) const () from /lib/x86_64-linux-gnu/libQt5Core.so.5 [...] #11 0x00007f924a9d9036 in QQuickWidget::resizeEvent(QResizeEvent*) () from /lib/x86_64-linux-gnu/libQt5QuickWidgets.so.5 #12 0x00007f924bd37947 in QWidget::event(QEvent*) () from /lib/x86_64-linux-gnu/libQt5Widgets.so.5
