I can't get into fc 26 anymore!

Yesterday, I was playing a rivals match with a friend when my PC crashed. Since then, I haven't been able to get back into the game. The game opens normally, but when it comes to loading a profile/save, I can't proceed any further. The login name is incorrect, and when I try to load the profile, it says it couldn't be loaded. I've already spoken to five of your agents and tried every possible troubleshooting step without success. From restarting the router to cmd commands and reinstallation, nothing has worked. The problem isn't on my end; my account must be stuck on some server or in some match. It can't be that no one is able to solve this problem! I used to work in the car rental industry, and the only thing you have to do there is kill an active session. You can't be serious. I'm asking for a quick solution to this problem! I also logged in from another PC and started FC 26, and got exactly the same error. Your cloud seems to have stored completely incorrect data!
