Ok guys I had the same problem when I did the 2.10 update, game used to freeze on the main menu, and sometimes let me go to GT mode but didn't let me go online. It was like that for a week or so, so I just stop playing it, and now i just try again and everything works fine now! I can even go online. So I don't know what really happen but my game is back to normal.
Surprised you could even get to the Main Menu.
So far all I can do is start a new campaign with second account until they get this fixed.
Indeed, I'm been playing the whole day today and not issue so far. Wonder what really happened, 'cause when I did the Update didn't let me go or do anything, and now it just suddenly working fine.
