EA FC 25 won't open.

I bought EA F C again last night. I downloaded it today and wanted to play. When I want to start the game, the small screen appears with the EA logo on it and it says in green: EA F C 25. After the gray loading bar below is full, this window closes and I am back in the EA Launcher. Today I tried to start the game on my main computer, which I have already reset, changed my D.N.S servers, restarted the PC and the Internet and I also tried it on my old computer. It can't be my system's fault as I have a good computer.
