Служба Windows находится в стартовом состоянии и не может сделать это в запущенном состоянии

---

I developed a windows service in C#. I followed some existing tutorials from google. In service.cs class the constructor is only holding the InitializeComponent() method. In OnStart() method I have written some code to open a port using TCPClient to connect via tcp connection to some other client. In that OnStart() method I am receiving a response from client using AcceptTcpClient() method and forwarding to an another class to process the client's response and send it back to the client. I maintained the coding fashion in ServiceInstaller and ServiceProcessInstaller and to start the service automatically adding up the event handler named AfterInstall and Commited. As I am installing the service, in service.msc it is showing service status as starting but the service is working as it should. Why the status is not showing running state?

Что я уже пробовал:

public partial class WinService: ServiceBase
{
      private static TCPListen listener = null;

      public Winservice()
      {
            InitializeComponent();
      }
      
      protected override void OnStart(String[] args)
      {
            loadconfig(); // Loading configuration data variables like port number IPAddress
            listener = new TcpListener(IPAddress, PortNumber);
            listener.Start();
            AnotherClass handler = new AnotherClass(listener.AcceptTcpClient);
            Thread thd = new Thread(new ThreadStart(handler.HandleSession()));
            thd.Start();
      }

      protected override void OnStop()
      {
            listener.Stop();
      }

      public loadconfig()
      { Method implementation }
}
