Application: plasmashell (5.20.5)

Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.8.0-41-generic x86_64
Windowing system: Wayland
Distribution: KDE neon User Edition 5.20

-- Information about the crash:
- What I was doing when the application crashed:

I disable secondary monitor. I must do this becouse there is not way to tell plasma to use the main monitor as primary monitor.

The crash can be reproduced every time.

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