Any ideas why the server I am launching would be crashing when a request is made to it?

Question

The server works perfectly when I run it directly. When I launch the server using the following code, it is closing and then restarting.. any ideas what I might be missing? My initial thought was the server was triggering the OnChange event when a request was being made to it. But no changes are logged.. I'm stumped.

   internal static class Program
{
    private static Timer _timer = new Timer
    { Interval = 1000, Enabled = true, AutoReset = true };

    private static DateTime _lastChange;

    private static void Main()
    {

        using var watcher =
            new System.IO.FileSystemWatcher(
                ConfigurationManager.AppSettings["RootWatchDirectory"])
            {
                NotifyFilter = NotifyFilters.Attributes
                               | NotifyFilters.CreationTime
                               | NotifyFilters.DirectoryName
                               | NotifyFilters.FileName
                               | NotifyFilters.Security
                               | NotifyFilters.Size
            };


        watcher.Changed += OnChanged;

        _timer.Elapsed += OnInterval;

        watcher.IncludeSubdirectories = true;

        watcher.EnableRaisingEvents = true;

        Console.ReadLine();
    }

    private static void OnInterval(object sender, ElapsedEventArgs e)
    {
        var now = DateTime.Now;

        var processes =
            Process.GetProcessesByName(server);

        var changeDetectWaitTimeInSeconds = int.Parse(10);

        if (processes.Length != 0) return;

        var ticksElapsed = now.Ticks - _lastChange.Ticks;

        var ticksToWait = TimeSpan.FromSeconds(changeDetectWaitTimeInSeconds).Ticks;

        if (ticksElapsed > ticksToWait)
