Argo Tunnel Agent service won't start on Windows Server 2019

I've created a config.yml file along with credentials file in `C:\Windows\System32\config\systemprofile\.cloudflared` I'm using Windows 2019 Server.

If I use psexec to launch a cmd prompt as the system account and invoke `cloudflared tunnel run` then the tunnel works as expected.
If I use service manager to start the service it immediately stops. There is no indication as to what the error is in any of the Windows event viewer logs.
The exact same configuration files and cloudflared.exe on Windows Server 2012 works correctly.

Is there any way to debug the errors caused by running the process as a service?
