Halo MCC not working after Reach Install

So before I start I have redownloaded MCC 3 times now over the course of the 2 days the Reach update has been live. Downloaded the whole 111.1GB game with no issues. Now I start the game and try to access the multiplayer social games to be hit with “Contacting server to get the latest matchmaking data” this never goes away. I press start to look at the “battle pass” style unlock system for reach’s armour and its greyed out saying “offline” when I am fully online as i can play other multiplayer games. If i go to settings and then network it says “network error unable to connect to the network services” eventhough I’m online. This has ONLY happened after the reach update and i dont know what to do. Has anyone else found this issue?
