My game runs only over Steam, doesn't show up in the EA App (other games from my Steam account like the Jedi games, Battlefront 2 and It Takes Two do show up), so I can't use that repair function.
I did however use Steam's gamefile integrity verification. It did not help. Still crashes when I try to load a save in the den. So here's my DxDiag report.
Also, this is the summary the crash report is giving me, if that could help too:
Unhandled Exception: EXCEPTION_ACCESS_VIOLATION writing address 0x0000000000000000
