I’ve been playing Halo Reach for a while without a problem on my Xbox One. I recently bought the $15 Anniversary map pack and installed it. Ever since, I have been unable to launch the game (it crashes before reaching the intro). I’ve tried restarting my Xbox, and reinstalling the add-on. Nothing seems to work, and now I can’t even start the game when I uninstall the add-on. What should I do about this?
Alright, I fixed my problem. I had to uninstall and reinstall Halo Reach, and then reinstall the map add-ons. Afterwards, everything ran properly, including the new stuff.
