Application: systemsettings5 (5.20.5)

Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.10.9-1-default x86_64
Windowing system: Wayland
Distribution: openSUSE Tumbleweed

-- Information about the crash:
- What I was doing when the application crashed:
  * Clicked something in System Settings.  I don't remember what.

- Unusual behavior I noticed:

    * Installed software updates (96?).

    * Rebooted.

    * After selecting Use Saved Session in System Settings,
    * I clicked Save Session in the App Launcher.

    * Logged out/in multiple times to check and adjust the saved session.

    * While logged out, I noticed a "virtual keyboard" icon and three
    Plasma options.  This was the first I remember seeing them.

    * Clicked the keyboard icon.  It activated and was labled 'British
    English'.  That's strange because my setup from install has only
    been 'US English'.  I dismissed the keyboard and didn't use it
    any further.

    * The three options were: Plasma, Plasma (Wayland), and Plasma
    (full Wayland).  I think Plasma was the pre-selected option.
    Selected full Wayland and logged in.

    * The desktop was scrambled.  All the windows of the saved session
    were on desktop 1, along with the two Konsole windows that were
    supposed to be there.  Another Konsole window and Firefox had been
    saved on desktop 2.  There were multiple partial renderings of
    the Konsole windows in different positions.  Except for the title
    bar, the Firefox window would flicker visible or not as I moved
    the cursor.  The title bar stayed there.  It didn't just depend on
    whether the cursor was over the Firefox window.

    * I moved Firefox and the extra Konsole to desktop 2.  Then,
    in desktop 1, I began looking for something in System Settings.
    Don't remember what.

    * The crash of System Settings happened when I clicked something
    there.  I don't think I was activating an app or changing a setting,
    but rather just traversing a menu hierarchy, although am not sure.

    * All the windows in all the desktops disappeared, except that
    the "System Settings - The KDE Crash Handler" dialog popped-up.
    I have since been able to open Konsole and Firefox while writing
    the bug report.

    * I was able to install the "missing debug packages" which then
    generated the crash information, but now, checking for software
    updates is failing.
