New crash information added by DrKonqi

systemsettings5 (5.22.4) using Qt 5.15.2

- What I was doing when the application crashed:

After applying changes to workspace behivor (specifically, removed corner and edge settings and set switch desktop on edge to "always enabled") the settings app immediately crashes.
