-- Information about the crash:
- What I was doing when the application crashed:
Since upgrading to OpenSUSE Tumbleweed snapshot 20220207, I've had issues with my second monitor in KDE.  When I boot, it never detects the second monitor, and then when I open the display configuration it struggles to enable the other monitor.  The second monitor disapear and appears in the list rapidly.  This time when I enabled the second monitor the dialog crashed, and that's what this crash report is.

The crash can be reproduced sometimes.

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
