Game made with Blueprints is working but with CPP its crashing

I have created two blank projects. One with Blueprints only and other with Cpp. I have not added any Blueprint class or Cpp class to the project. Then I packaged both the projects for Android with exact same configuration.
Now when I push both the built games to my Android device, Only Blueprint’s game runs. The Cpp Game crashes immediately I launch it and it crashes every time I launch it.
Where should I look for the fix?
Should I even use the Unreal Engine for Android Development or Should shift back to Unity?
