Hi, I configured my GPU Passthrough (Nvidia RTX 4060 Ti, Ryzen 7 7700) to Gaming HVM without any troubles using only this guide.
I haven’t installed anything yet on VM, I was just playing around in demo mode of PopOS which have ISO version with installed already Nvidia drivers to check if everything is working and everything is fine. Only problem which I met is problem to attach my keyboard and mouse to HVM, when I try there’s error like this

I tried to attach my keyboard to any other cube from template and it’s working so it’s something wrong with this HVM. But when I did this I had to unplug and plug my keyboard because when I unassigned it from this qube I wasn’t able to use it and as I checked is the same with any other device and any other VM. I had to unplug device to be able to use it after attaching it to any VM.
I completely don’t know what might be wrong there because I’m completely new in QubesOS world. I would be grateful for your help, thank you in advance!
