Are you using a Windows 11 ISO downloaded from Microsoft's website directly?

@streamcfd Can you make sure no other GPU PV VMs are started when you start this VM?

[streamcfd]

Yes I am using Hyperv and that causing this issue.

If I start sandbox vm first, then no issue

[jodiecunningham]

I think it's probably one of your GPUs not liking the amount of sharing. Is there anything you can set to not have it share the intel GPU with your VM?
