Display Link in a Crashing Loop

As this is going on, the screen recording icon is dropping (I lose my monitors) and coming back (monitors turn back on). This is occuring every 45 seconds or so.

I've used the End User Cleaner and gone back Display link 11 as well and no luck. Since updating to Sequoia 15.3.2 and updating to Displaylink 12, the Displaylink is acting as if the thunderbolt cable is being unplugged and plugged back in again every 45 seconds or so. I know the issue does not lie in the hardware as I have tested the cable with my Iphone plugged into the dock and it will hold a consistent connection with the Iphone and both thunderbolt inputs on the Macbook are operating correctly as well.



Current Setup:
- Macbook Pro M4 - Sequoia 15.3.2
- Wavlink Dock WL-UG69PD 24
- 2 LG UltraFine Monitor 27" 4K UHD 60Hz 5 ms IPS Monitor (27US500-W) connected via DisplayPort

If the manufacturer of your docking station (Wavlink) has not been able to provide support, then I would suggest reporting the issue to DisplayLink directly by following the process outlined here --> https://support.displaylink.com/know...to-displaylink

There is a known problem with macOS 15.3.2 that's been affecting many folks.

If you look at the details of several recent posts, this all began with the update to 15.3.2

Its probably worth it for you to also report and send in diagnostic info, but I have been able to recreate it with multiple machines and multiple displaylink adapters.
