-- Information about the crash:
Hello there,

I'm experiencing a crash in the following scenario:
- 2 Displays (1x HDMI, 1x DP), USB Mouse/Keyboard/Webcam are plugged into a HP USB C Dock G5
- The Dock is connected to my PC via the USB-C Out on my NVIDIA GeForce RTX2060 Super
- Plugging out the Dock causes plasmashell to crash 
- Upon replugging the Dock the crash reporter (source for this report) is shown

If there are any things I can do to help triaging this crash please let me know.

Regards,
Martin

The crash can be reproduced sometimes.
