I have the same problem with XFX RX6700XT 319 quik, but with Hyper-V machine running from Windows server 2022.
Resetting the VM just killing RX6700 and i'm getting an error 43 in device manager.
Problem solving after I'm rebooting the host. But after rebooting VM i'm getting error 43 again.
There is no any problem with RTX3080 in the same setup!
I'm using DDA (deploying-graphics-devices-using-dda)
my board MSI x570 gaming plus
Have you found any solution???
