Created System.ServiceProcess Service fail on Win Server

Trying to build a background service with autostart in the background. Core login was executing from OnStart - Modified code after several failure attempts to start by finally stripping out the business logic and trying to test only the service part. Reduced to the core essentials below for repro.

Program.cs

namespace wserv
{
    static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        static void Main()
        {
            ServiceBase[] ServicesToRun;
            ServicesToRun = new ServiceBase[]
            {
                new Service1()
            };
            ServiceBase.Run(ServicesToRun);
        }
    }
}

Service1.cs

namespace wserv
{
    public partial class Service1 : ServiceBase
    {
        public Service1()
        {
            InitializeComponent();
        }

        protected override void OnStart(string[] args)
        {
        }

        protected override void OnStop()
        {
        }
    }
}

Compiles with no errors on buidserver (Winserver 2019) and install with nssm works ok. However any attempt to run on Windows Server fails with the service not starting.

Expectation: Should run and do nothing (works on Win10) fails on Winserver

Eventlog has the folllowing error

Service cannot be started. The service process could not connect to the service controller

Fails to start on: Win Server 2019 Datacenter (AWS) .net4.8 Win Server 2016 Standard (VMWare) .net4.8

Works as expected: Win10 Enterprise 22H2 .net4.8

build with .net4.8 Framework on Windows Server 2019 Datacenter.
