GPU-Z shows that on 1st GPU 215+Mb videomemory is in use... That's why it's not enough to mine eth.
In ports of 1st GPU inserted something? If you use igpu Windows didn't use other GPU memory... Something wrong here...
nothing inserted at gpu 1 and already set igpu enable in bios.

Don't know than what's wrong with your comp... Try to search info about your motherboard... Maybe it's need to update mobo bios...
Try to delete AMD drivers via DDU and install again.
Ok, will try again. Thanks bro

I think it is something due to windows updates. I solved it by updating all ( 19.03, with 365 days delay on feature updates )and reinstalling video driver ( DDU...than 20.4.2). Maybe reinstall windows if that don't help
