Unable to play Halo 3 ODST

After updating my console I’ve been left unable to play Halo 3 ODST, I get prompted to download the game from the store, although the game is already installed on my console. I tried some basic troubleshooting steps as advised by the xbox support team, although I’m still unable to play. Any help will be appreciated.

How are your trying to access ODST - from within the MCC itself (after launching MCC) or from your Games and Apps area?
