Clamshell mode no longer working - Sequoia15.2

[skimmiks]

I usually use my MacBook Air 13" in clamshell mode connected to 2 external monitors using a Plugable Display Docking Station with DisplayPort. I had no problem using it with DisplayLink for 2+ years. I also updated my MacBook with every update that came along.

No problems until the Sequoia15.2 update recently. Now I cant use clamshell mode and need to have my MacBook open in order to use the external monitors. If i close the laptop, the screens go black.
I've used the End-User Cleaner and uninstalled display link and re-installed it using the newest version 1.11.0.... but still no dice. Works only when the laptop is opened.
