Application: plasmashell (5.18.5)

Qt Version: 5.14.2
Frameworks Version: 5.70.0
Operating System: Linux 5.3.0-51-lowlatency x86_64
Windowing system: Wayland
Distribution: KDE neon Testing Edition

-- Information about the crash:
- What I was doing when the application crashed:
I'm starting a wayland session (Ubuntu Neon testing 08.05.2020) and plasma crashes several times. 
When manually starting plasma from krunner the same thing happens.
- Unusual behavior I noticed:

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
