Display Link Stopped working on 3 monitors with M1

I am also having an issue with my two monitors. (only one screen is working)

I have two identical DELL monitors that worked fine before, up until 2 hours ago. The only thing that I did and that seems to have messed up everything is that I updated my OS to Tahoe version 26.3.1 (25D2128)

For context, my monitors are connected to a Dell Universal Dock UD22 using HDMI and DisplayPort. I have been using this setting for the past 6 months with no issues with version 14.

I tried to update to version 15, but ended up having the same issue. I still have a single monitor working.
