Tips for progressing past task sequence step "Run PowerShell Script"

[Xavierstarr]

I have a few PowerShell Scripts that I have run between Windows Update Pass 1 and Pass 2

I have one script that pops out a grid view to select an item from a list to trigger a specific app install via invoke-webhook to $env:TEMP/Installer.exe then start-process $env:TEMP/Installer.exe

it installs ok but task sequence does not progress pass this step and we need to manually terminate and trigger PSDFinal.ps1 to cleanup.

I have exit codes and try catch methods, the script runs fine but it's not triggering task sequence to progress.

even tried:

$process = start-process $env:TEMP/Installer.exe
Write-Output "Waiting for install to complete"
$process.WaitForExit()
Write-Output "Installation completed"
exit 0

any tips to help task sequence to detect this is done and progress?

The other scripts I have are just debloating and branding which work fine, any tips would be lovely.
