No MSFT_Disk objects found with property 'Number' equal to '3' After Updating Drivers

[LewisWildgoose]

Just recently updated my GPU drivers users Nvidia Geforce Experience, however, when trying to run the update drivers script to update the VM drivers, I get the following error:

PS D:\Downloads\GPU-Hyper-V\Easy-GPU-PV-main\Easy-GPU-PV-main> ./Update-VMGpuPartitionDriver.ps1 -VMName "GPUPV" -GPUName "AUTO"
Mounting Drive...

Copying GPU Files - this could take a while...

Then a load of errors form because it couldn't mount the drive. If I try rerun the command it complains about the process being in use. My formatting of the command should match:

$params = @{
    VMName = "GPUPV"
    SourcePath = "D:\Downloads\GPU-Hyper-V\Win10_22H2_EnglishInternational_x64v1.iso"
    Edition    = 6
    VhdFormat  = "VHDX"
    DiskLayout = "UEFI"
    SizeBytes  = 40GB
    MemoryAmount = 16GB
    CPUCores = 4
    NetworkSwitch = "Default Switch"
    VHDPath = "D:\VMs\HyperV"
    UnattendPath = "$PSScriptRoot"+"\autounattend.xml"
    GPUName = "AUTO"
    GPUResourceAllocationPercentage = 50
    Team_ID = ""
    Key = ""
    Username = "GPUVM"
    Autologon = "true"

If I list both Get-Disk and Get-PhysicalDisk:

Additionally, my VM only has the one HDD attached: https://i.imgur.com/PEqSibD.png

Any ideas? This is driving me up the wall.
