-- Information about the crash:
I often connect my laptop to a Dell WD22TB4 dock. On this dock, I have 2 external 4K displays connected and when connected, I disable my laptop's internal display. This crash happens when I disconnect from the dock and the laptop's internal display re-enables.

The crash can be reproduced sometimes.
