Установленные приложения должны содержать только Джанго приложения, которые вы хотите включить в вашем приложении, я вижу, вы добавили приложение и app.views. views - это не приложение, это файл python, присутствующий в каталоге приложения, удалите его и попробуйте выполнить миграцию.

Также, пожалуйста, добавьте пользовательские приложения после стандартных приложений django для лучшей практики.
