Issue with Web browser Control C#

Question

I am using Webrowser control to go to a url and do a step and that is it. The issue i am facing is the control works fine for exactly 2 times and then it stops working and does not load the url any more than i realized if i close the application and ran again it again works twice and then same thing . I have tried like this approx 5+ times happens each time so this is strange behavior.

The control is inside a thread.

 var th = new Thread(() =>
            {
                using (var br = new WebBrowser())
                {
                    br.DocumentCompleted += browser_DocumentCompleted;

                    br.ScriptErrorsSuppressed = true;
                    br.ScrollBarsEnabled = true;
                    br.AllowNavigation = true;

                    br.Navigate(urltoRun);
                    Application.Run();
                }
            });
            th.SetApartmentState(ApartmentState.STA);
            th.Start();
            th.Join(60000);
            th = null;

And browser_DocumentCompleted:

    private void browser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
    {
        if (!string.IsNullOrEmpty(htmlResult))
            return;
    // DO SOMETHING...
    }

I had the same problem and I had an exception, so make sure that "common language runtime exceptions" is checked in Exception Settings ( ctrl + alt + e will open the window).

If the webbrowser control isn't that friendly, you can try using "Cefsharp" for winform.
