Winapp driver not support web elements

I’m automating my Windows application.

I’m using Winapp driver and Java language for automation. I am capturing the web elements using UI Spy Tool.

My application is loading, still I can’t automate the login page.
I’m getting the following error:

My Code:

public class Reporter 
{

    private static WindowsDriver<WindowsElement> driver;

    public static void main(String args[])  
                           throws MalformedURLException, InterruptedException 
    {
        DesiredCapabilities capabilities = new DesiredCapabilities();
        String homePath = System.getenv("USERPROFILE");
        capabilities.setCapability("app",  homePath + "\AppData\Local\Apps\2.0\HHCZT7OJ.D37\61K3K288.OXH\base..tion_6e5be371fe594b2d_0001.0000_aad96dff3b16369b\");
        WindowsDriver Session = new WindowsDriver(new URL("http://127.0.0.1:4723"), capabilities);

        Assert.assertNotNull(Session);
        Session.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);

        DesiredCapabilities Appcapabilities = new DesiredCapabilities();
        Appcapabilities.setCapability("app", "Root");
        WindowsDriver AppSession = new WindowsDriver(new URL("http://127.0.0.1:4723"), Appcapabilities);
        Thread.sleep(5000);

        WebDriverWait wait=new WebDriverWait(AppSession, 30);

        AppSession.findElementByAccessibilityId("txtUserName").sendKeys("r_nave");
        AppSession.findElementByAccessibilityId("txtPassword").sendKeys("naveen");
        AppSession.findElementByAccessibilityId("btnLogin").click();
    }

}

Error::

Now it’s working for me that I put thread.sleep 20000
