After Monterrey -> Ventura upgrade, one of monitors recognized as "No monitor"

I have two monitors connected to Dell Universal Dock D6000:
- Asus VS24A connected via HDMI.
- Asus PA278QE connected via DisplayPort.

I was running MacOS Monterrey, and had no issues with the two monitors being recognized correctly (there was an issue that after waking from sleep, sometimes PA278QE would be missing, but upgrade to DisplayLink Manager 1.8.1 solved the problem. The VS24A would show up on DL Manager as the first one, and PA278QE as the 2nd.

However, after upgrade from Monterrey to Ventura, the VS24A monitor shows up as “No Monitor” rather than "VS24A", and is stuck at 640x480 resolution with no apparent way to change it to higher resolution. So far I have not figured out any way to fix this...

This went away (at least for now?) after power-cycling D6000. Now I feel stupid - I tried rebooting the laptop, but somehow did not try powercycling the dock before posting here.

Unfortunately, rebooting, reinstalling, flashing, and generally any manipulations with the D6000 do not help, DP and hdmi do not see the monitors (LG and huawei)

Same issue here in clamshell mode with 2 external monitors and OS 13.4.
