I have the same issue with usb-c alone, this has been occuring for months now on Big Sur. There are reddit posts about it from months ago.
it's a big sur issue, and how it was released like this is beyond me.
already tested the monitors using hp running windows and they work fine. i just upgraded like a week ago and now they monitors are not being detected. both of them.
