Windows testing

I am trying to open Chrome and enter my url but I can see the browser opening but closes in seconds…

public class FormbayWeb extends FbWebExtReport {
public AppiumDriver driver;
public WebDriver webDriver;

@BeforeTest
public void winAppSetup() throws Exception
{
    try
    {
        DesiredCapabilities caps = new DesiredCapabilities();

        caps.setCapability("platformName", "Windows");
        caps.setCapability("platformVersion", "10");
        caps.setCapability("deviceName", "WindowsPC");
        caps.setCapability("app", "C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe");
        
        URL url = new URL("http://127.0.0.1:4723/wd/hub");
        driver = new AppiumDriver<WebElement>(url, caps);
        driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);

    }

    catch(Exception ex)
    {
        System.out.println("Cause: "+ex.getCause());
        System.out.println("Message: "+ex.getMessage());
        ex.printStackTrace();
    }

}

@Test
public void SampleTest(){
    System.out.println("Browser is open");
}

@AfterTest
public void closeApp() throws InterruptedException, IOException
{
    driver.quit();
    System.out.println("Browser Closed");

}

}

FbOneTest

public class FbOneTest extends FormbayWeb{

@Test
public void OpenTrading() throws InterruptedException, IOException {
    ExtentTest openTrading = extent.createTest("Trading is open", "Open Trading in Browser");
    openTrading.log(Status.INFO, "Trading Test Started");

    driver.get("www.google.com");
    openTrading.log(Status.PASS, "Navigate to trading portal");
    Thread.sleep(10000);
}

}
