What App Center service does this affect?
testing on ios simulators / android emulators

Describe the bug
Hi I have a Xamarin UI test project with tests apps on iOS and Android simulators. I have recently updated nunit & xamarin.uitest to the latest versions. Now when I start my app on a simulator I get the error: Exception has been thrown by the target of an invocation

To Reproduce
I start the app as follows: (the app is started on the simulator - but then the test crashes)

IApp myApp =  ConfigureApp
            .iOS
            .InstalledApp(pathToApp)
            .DeviceIdentifier(123456-123456)
            .PreferIdeSettings()
            .EnableLocalScreenshots()
            .WaitTimes(new WaitTimes())
            .Debug()
            .StartApp(ClearAppData);

Expected behavior
With the app now visible and running I expect to be able to test it. With the variable myApp I should be able to run my tests. But the error occurs in the ConfigureApp and the variable myApp remains null.

Screenshots
none

Desktop (please complete the following information):

The following is the log output after trying to start an ios app:
