vrealize blue print fails to execute cloud-base-init powershell part

edit

My Vmware Vrealize blue print works perfect on my windows 2019 build templates exept for when I tried to do the cloud-base init section for powershell to configure new VMs after the customization spec instead of a ps1 scritp ran on the machine. I'm wondering if its something I have done incorrectly in the code? or if its an issue with the cloud base init installation on my base template. I start the section

cloudConfig: | #ps1_sysnative Start-Transcript -path "C:\temp\cloudbase-init-firstboot.log" -Append -force Import-Module Activedirectory

I can provide logs if needed
