-- Information about the crash:
Connecting the external docking station with power, LAN and a HDMI-Monitor connected crashes plasmashell since 6.3. It is my work setup and usually happens once in the morning probably after the computer was sleeping overnight. Disconnecting and reconnecting the station throughout the day doesn't crash usually.

The crash can be reproduced sometimes.
