Can't get Windows 10 VM with GPU Passthrough To Boot

[FiNakoma]

Been having loads of issues getting a Win 10 VM with GPU passthrough for my Asus AMD 6600XT. I had it working on an old VM with virtually identical settings to this one. The only difference is that I'm accessing an NVME directly instead of using a VDISK image. I've since broken that VM completely so can't access it anymore. 

 

I can get into Windows if I use the standard VNC driver but I keep running in to the following error:

I've tried loads of guides tried about everything I can find on google/unraid forum/reddit.  Stepping away before I lost my mind.. 

 

Here's my VM config:

Removing the following from the VM XML file and boom VM boots absolutely fine and I can see my GPU in device manager:
