Invalid app config

Hello,
Could you please guide me why I am getting bellow error in application when running on emulator? I am have tried start version as well as final version of your code I am getting same errors in both cases. I have attached some logs here in this post.

When I click on any button I am getting above mentioned error in logs app is not able to recognize anything.

No source file, test, or entry point is named; begin by reproducing the app on the emulator and inspecting the application configuration around the button actions and reported log messages. Done requires identifying why the app reports “Invalid app config” and documenting or implementing a verified correction, but the report lacks enough detail to locate that change.
