Display Link Suddenly Stopped Working

hi,

monday everything worked fine but today only 2 of my 3 additional screens are working.

set-up
macbook air m4
Tahoe 26.3.1
3 external screens
3 screens are connected to with hdmi
displaylink hardware

the software is showing the 2 screens as active but no longer showing the 3rd screen at all in the software visual which would mean it is not seeing the screen at all.
