Unfixable Error Code 216

I have owned Star Wars Battlefront II for years now but a while back it stopped letting me load into any multiplayer game at all. I keep getting a split second glance of the troop selection screen at the beginning of every game and then it kicks me out and displays error code 216. I have researched every possible solution and not a single one has worked for me. I play on Xbox One S, so I have cleared my cache and MAC address, changed my DNS, tested my NAT type and all my connections, and also clearing my reserved space before reloading the game. It seems that there is no fix to this and I am unsure what to do.
