my game does not work anymore

I went on vacation at the beginning of March and my game was working perfectly. When I came back and decided to play again about a week ago, I installed the recommended update. Since then, I haven't been able to load my save anymore.

Even without any mods, after repairing the game, and even when trying to recover my save, the issue is still there.

Whenever I try to load my game, it crashes, and EA shows me a message saying that the game could not be launched due to an error on our end. Please try again later. However I did try again later (even several days later), and it's still the same problem ! 

When I try to recover my save, the loading screen just keeps loading indefinitely! 

I am very pissed, and I don't understand how an update that is supposed to fix bugs can completely break my game (and probably cause me to lose my save)
