MCC Reach on PC isnt saving campaign progress

Hello,
I got MCC for PC off steam. The game isnt saving any kind of game changes such editing your spartan or campaign progress after you quit to desktop. If you start campaign in quick start, save and quit to the menu you can load your save. If you save and quit then quit to desktop it doesn’t save anything.

I also cant get on multiplayer because it says easy anti cheat isnt enabled.

Thanks.
