Application: plasmashell (5.22.90)

Qt Version: 5.15.3
Frameworks Version: 5.87.0
Operating System: Linux 5.11.0-37-generic x86_64
Windowing System: Wayland
Distribution: KDE neon Testing Edition
DrKonqi: 5.22.90 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
Adding various widgets to new Application Panel

- Unusual behavior I noticed:

All panels and apps disappeared. After several alt+tab attempts I was able to click the app crash icon and pull this dialog box up

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
