Service rhino.compute won't start

Process is able to start interactively, but not via service start. Error displayed is ‘access denied’. In the event log it is below. ( Note: c:\projects\ does not exist on our Server 2019 instance). This is after following the build guide here: Deployment to Production Servers with C#, VB

Any help is appreciated.

Service cannot be started. System.IO.IOException: The handle is invalid.
