Hi team,

I occur the app is sometime crashing when I try to load license, it happens about 50% of time.  
Package version: 14.2.1

I loaded the license in App.cs.OnStart()  
protected override async void OnStart()  
{  
base.OnStart();  
System.Diagnostics.Debug.WriteLine(“App-OnStart”);  
// Load in the Loading page while we wait for services

```
   await SampleGoLightInjectStartup.RegisterLicense();

```

}

Interesting that the error is gone after changing the app initialize step…

Hi Jimmy,

In fact, we saw this issue as well and have fixed it in the latest beta. The fix will be available in the upcoming release early next week as well.

Thanks,  
Ben
