Tahoe 26.2 monitors randomly on and off

Please disregard:

Not a driver issue, hardware was failing. Used a different manufacturer and it works fine.

After upgrading to Mac Tahoe 26.2 (25C56) my monitors are randomly going blank and after a few seconds come back, this is randomly repeating. Running DisplayLink Manager 15.0.0 (Build 22) I'm using Wavelike WL-UG69PD8 Pro. I have 3 4k Monitors attached.

If I connect one Monitor to HDMI, it works, but the other two on the WavLink have the same cycling problem every time I do any activity on them.

This is rendering the dock useless.

I was having this same issue since installing Tahoe and upgrading to the 15.0 software. My issues seemed to have been fixed however by replacing the USB cable (I had been using the cable the dock was originally sent with for a couple years now).
