[XZ123]

Windows writes error 31 when trying to install the driver, I get a blue screen with an NVIDIA driver error

What is the output of cat /proc/cmdline?

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt pci=nommconf pcie_acs_override=downstream,multifunction nofb nomodeset video=vesafbff,efifbff"

nofb nomodeset video=vesafb:off,efifb:off" does not work anymore since Proxmox 7.2. Use this work-around instead when you passthrough the boot GPU.
Do you really need pcie_acs_override=downstream,multifunction? It is very unsafe. Why do you need pci=nommconf?

Maybe your NVidia GPU additionally needs some special work-around but I don't know.
