So, excuse the question again: but what do I do?
If I have to remove the problematic extensions, I have to totally redo the app from scratch.
How do I manage this situation?
moreover, if even with 0 blocks the app crashes, it means that the problem could also be the project itself, because 0 blocks means 0 components and 0 extensions, right?
EDIT: in searching for a solution i found this post, the problem was solved
