halo pc unplayable

it started out by me not being able to join my friends or connect to matchmaking, but atleast i could play campaign or offline firefight. i searched for a solution online, one of them said to sign out of your microsoft account ingame. i did that, but now i cant even get to the main menu. every time i try to play the game, i get “Sign in error. Error encountered while signing into xbox live” but it doesn’t even give me the prompt to sign into xbox live?? the game was working perfectly until this just randomly started out of nowhere yesterday. anyone got a fix?
