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

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"

INFO   : Finding and copying driver files for NVIDIA GeForce RTX 3060 to VM. 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.
