The term 'C:\Program' is not recognized as the name of a cmdlet

Where are you running it?

On-prem Azure DevOps Server

Version of Extension/Task

10.3.10

Expected behaviour and actual behaviour

Expected Pester to run when executed by an agent installed in the Program Files directory.

However, it looks like it's not quoting itself:

powershell.exe C:\Program Files\vsts-agent-win-x64-2.160.1\_work\(snip)\10.3.10\Pester.ps1

Here's the full script output:

Starting: Run unit tests

Steps to reproduce the problem

Very simple task usage in my DevOps pipeline:
