Note that there is a separate issue where Shift 2 crashes when doing quick race or some career events (may be most of them, but not all of them). The only solution so far is to disconnect the PC from the internet. I and other players have had this problem. Although nothing was changed on the PC (client) side, this crash bug was probably there all along, but some change on the server side has now exposed that bug. Again the fix is to disconnect the PC from the internet.
In my particular case, I'm able to reproduce this bug, without being signed in, since my password has changed since I first played Shift 2. So although not logged in, having internet connected results in crash at some career events or quick race, but disconnecting my PC from internet solves this problem.
