Second monitor no longer working on my Mac

My monitors have worked peacefully for months. Just yesterday the second monitor has stopped being recognized. The first monitor works fine, and when I switch the HDMI cables in the dock the functional monitor switches and the second monitor works just fine but the first is not recognized.

Configuration:

14-inch MacBook Pro, M1, 2021
MacOS: Sequoia 15.1
Dock: Kensington SD4900P
DisplayLink version: 1.11.0 (build 28)

I've tried turning everything off, updating my Mac to the current version of sequoia, uninstalling and reinstalling displaylink manager, and power cycling the doc (both with the button and removing the power cord for 1 min). Nothing has worked.
