I installed windows 10 with Radeon rx 5500xt passthrough and ssd passthrough
everything went good, until windows update installed the radeon rx 5500xt driver, then the screen went black, and every time now I run windows, it freeze while booting (doesn't complete the boot).

I fixed it by setting the cpu type to "host" (instead of kvm64)
and setting the pcie flag:
hostpci0: 0000:0a:00,pcie=1,x-vga=1
