-- Information about the crash:
When a "Dell Thunderbolt Docking Station (WD22TB4)" is plugged into the USB-C port of my laptop (HP_Spectre_x360_Convertible_13-aw2xxx),
the system's setting application crashes.

Actually other system applications, such as the "info center" also crash repeatably.

The Docking Station is plugged into an ATEN-CS17916 KVM Switch.
The USB Peripherals are
* Dell Keyboard
* Dell Mouse

The HDMI display is an "ASUS VP28U"
Resolution on the External Monitor: 2560x1440 60hz
Resolution on the Internal Monitor: 2560x1440 60hz
Scaling on both monitors is 1.5

The crash can be reproduced every time.
