[Problem/Bug]: System.InvalidCastException occurs when setting AllowHostInputProcessing to 'true'

[bhavin-prajapati]

What happened?

I have a UWP Xbox App with a WebView2 container that points to a web URL. I've mapped the gamepad keys to manually send the KeyboardEvents into the WebView2 so I'd like to set AllowHostInputProcessing to true so the same events don't get invoked within the webview. However, when I set the AllowHostInputProcessing to true in CoreWebView2ControllerOptions, it throws 'System.InvalidCastException'. I have the latest version of WebView2 v1.0.3537.50.

Importance

Blocking. My app's basic functions are not working due to this issue.
