Can't load W10 VM - Ryzen + NVIDIA GPU.

[braydination]

I have been having some real struggles over the last week to get my W10 VM running after completing my first build.

Managing to get Windows installed through VNC, i proceeded to try and passthrough my GPU following as many videos from SP1 as I could find.
I've successfully separated all my IOMMU groups and then eventually managed to get 1 boot onto my monitor. The next day I decided to try and passthrough my USB devices so I could connect an external HDD to begin transferring data.

Ever since, I have not been able to boot my VM at all. I have gotten to the point where I have a vbios installed and no more error messages, but the VM just wont boot up, or the whole server freezes and crashes.

I don't even know what information to share anymore as I have just hit a roadblock and don't know where else to try and get any answers...
