Starting a process from Azure deployment agent task

Question

Hi,

I have configured my Azure release pipeline with a deployment group job that is targeting a pool of windows machines.
After successful deployment, that job is running a power shell script task which attempts to start a windows executable with GUI on the target machine. Then it waits for 1s and checks if the executable is running. I'm getting a valid process ID back in the log file of the deployment job.
But when I check on the PC after the release is complete I don't see the executable running and task manager shows no process with the logged process ID.
Is there something I need to do to make sure it keeps running when the agent has finished its work?

The agent is running as the same user which is logged on.

This is the power shell script

$p = Get-Process -Name $(Process) -ErrorAction SilentlyContinue  
if ($p) {  
  Write-Host "$(Process) is running with PID" $p.Id -Background Green  
} else {  
  Write-Host "$(Process) is not running - starting $(PathToExecutable)"  
  Start-Process -FilePath "$(PathToExecutable)"  
  sleep 1  
  $p = Get-Process -Name $(Process) -ErrorAction SilentlyContinue  
  if ($p) {  
    Write-Host "$(Process) is running with PID" $p.Id -Background Green  
  } else {  
    Write-Host "Could not start $(Process)" -Background Red  
  }  
}

And an example log file
