Cant access Halo 2

Games Halo: The Master Chief Collection

I’ve downloaded and installed Halo 2 but I cant seem to access it in game.
Checking the Steam Discussions, it seems a lot of other people are in the same boat.

Does anyone have a solution?

Nope…Just wait!

If you’re on Steam try restarting it - that fixed it for me.
