After installing the plugin for visual studio 2017, i get a "object reference not set to an instance of an object" error when trying to create an app. I expected the creation window for the app. Creating an workspace works oke, but when I want to add an app to my workspace I also get this error. Am I missing something here?

I installed the plugin on an enterprise edition of Visual Studio version 15.7.1 and the .NET Framework Version 4.7.03056.
