MacBook M1: new dock worked for 1 day

OK. It's working again. I never heard back from uGreen support, so I just tried these steps on my own. Here are the steps I took, and I'm not sure which one addressed the root cause of the issue:

1) Uninstalled all DisplayLink drivers and any other related files and reinstalled the latest driver (mar 23, '23 version)
2) Plugged in new uGreen device (3rd one of the same model). I carefully followed the diagram showing where the power supply input should be coming IN, where the hub should be running out to the laptop.
3) I changed the DisplayPort version on Monitor #2 to from version 1.4 to version 1.2.
4) There are 2 groupings of HDMI/DisplayPort inputs on the hub - we'll call them Group A & Group B. I made sure that monitor#1 which uses HDMI was plugged into Group A HDMI port. Then I ensured that monitor #2 which uses DisplayPort was plugged into Group B.

Now it works. Fingers crossed it will keep working.
