Hi,
I've started using the WinAppDriver to start testing the windows desktop application CCleaner using the WinAppDriver.
Approximately 50% of the time I get an issue during the launch of the application, and I can't figure out what the problem is. Can anyone see where I'm going wrong? It seems random, sometimes Appium restart fixes it, sometimes not, but I'd like to resolve this so I can start using these tests in a CI process.
Here's the code in question:
public static class Application
{
private const string AppDriverUrl = "http://127.0.0.1:4723/wd/hub";
private const string CCleanerAppId = @"C:\Program Files\CCleaner\CCleaner64.exe";
private static WindowsDriver<WindowsElement> CCleanerSession;
private static void initialiseAppiumDriver()
{
DesiredCapabilities appCapabilities = new DesiredCapabilities();
appCapabilities.SetCapability("app", CCleanerAppId);
appCapabilities.SetCapability("platformName", "Windows");
appCapabilities.SetCapability("deviceName", "WindowsPC");
CCleanerSession = new WindowsDriver<WindowsElement>(new Uri(AppDriverUrl), appCapabilities);
When the Appium session launches, CCleaner starts up, but it feels like either Appium 'loses' its connection to the app, or my CCleanerSession doesn't get created properly. In the code when debuggin the CCleanerSession above is null.
Error from Debug:

In the Appium console I see this:

Many thanks, sorry if its something obvious I've missed!
