Thank you very much for your feedback, my problem is solved. The problem came from the fact that my boss had not read and accepted some new conditions from apple for another application but from the same account. And a tierece application that is not up to date in terms and contracts will prevent the creation of a new application. Hopefully this helps someone in the future, thanks again for your feedback and have a great day.

hello, thank you very much, even with full access it doesn't work, and normally everything else is fine. The problem is that Apple doesn't really give any details about why it doesn't work.
