Morning Carlo! I followed this instruction to see what happens. The following result occours:

Running on 17A306f
Run command, disconnect DisplayLink device, restart the computer.
Computer boots normally with just the laptop and Apple Monitor plugged in over Thunderbolt.
Plug in DisplayLink with HDMI monitor attached.
WindowServer crashes, brings me back to login screen. Login screen is sky blue with a mild gradient, the background is not the standard background.
When trying to log in the WindowServer crashes and sends back to login. Repeat until you disconnect the HDMI and login screen returns to normal and login process is successful.
