PLZ HELP unable to load non dlc maps in halo4

So recently ive started playing halo 4 again and everything went fine but now everytime i start halo 4 it’s really buggy. A few examples of this are it takes what seems to be ages to fully load up to the main menu. as well as when i start my network setting are set to “my xbox” by default. I can still play dlc match making but anything on normal maps doesnt work. any help is greatly appreciated.

re-installing the title update works but only until i relaunch the game
