Game Crashes when Online

Been having this problem since Sunday. Whenever I do ANY sort of gameplay while online, the game freezes then sends me to the dashboard. I’ve tried campaign, custom games, matchmaking, and even viewing games in Theater. I’ve uninstalled/reinstalled the game twice, all with the same results. Approximately 30-45 seconds into a game, it crashes.

However, when I took my console offline, I was able to play the campaign no problem. So the only thing I’m able to do right now is offline campaign, which wouldn’t be a problem considering I haven’t beaten them yet, except that none of my achievements will register until I come back online. And I’m not even sure if they’ll unlock with all the other issues that achievements have been having.

Please get this fixed soon.

Same problem here.
Its really a shame.
