I have the same issue with my iMac 2021.
After I shut down my mac, it restarted and I got a Problem Report for MacOS prompt saying it was a Kernel version: Darwin Kernel Version 20.4.0. I searched the issue right away in Google and found out about this thread. True enough, I'm using my Baseus USB-C Dock for the first time. Hope they'll fix it soon.
