'Dispatcher.PushFrame hang issue

       Task<string> executeScript = webView.CoreWebView2.ExecuteScriptAsync("apm.module().hasUnsavedData();");
        System.Timers.Timer timer = new System.Timers.Timer();
        DispatcherFrame frame = new DispatcherFrame();

        string hasUnsavedData = "True";

        executeScript.ContinueWith(_ =>
        {
            if (executeScript.IsFaulted) hasUnsavedData = executeScript.Exception.Message;
            else hasUnsavedData = executeScript.Result;
            frame.Continue = false;
        });
        ComponentDispatcher.PushModal();
        timer.Enabled = true;
        frame.Continue = true;
        Dispatcher.PushFrame(frame);
        timer.Enabled = false;

        return !Convert.ToBoolean(hasUnsavedData);

I have this code to get the value from Async call and the calling method is synchronous, code is working at many places but crashes somewhere on "Dispatcher.PushFrame(frame);". Can someone please help me with this issue?
