Error When Executing Convert-WindowsImage in PowerShell 7.0 in Windows 10 v.1909

Hello:

I am attempting to create a VHDX drive in which I can execute Windows 8.1. I am using version "10.0.14278.1000.amd64fre.rs1_es_media.160201-1707" of Convert-WindowsImage. The calling sequence I am using for Convert-WindowsImage is as follows:

E:
CD "Temp Files\Temps - U1"
. .\Convert-WindowsImage.ps1
$ConvertWindowsImageParam = @{
    SourcePath = "Windows 8.1 Enterprise.ISO"
    VHD = "V:\Windows 8.1 Bootable.VHDX"
    IsFixed = $True
    DiskLayout = "UEFI"
    Edition = "Enterprise"
    Verbose = $True
    VHDFormat = "VHDX"
    EnableDebugger = "None"
}
$VHDx = Convert-WindowsImage @ConvertWindowsImageParam

The error I receive is:
