Assistance please

My digital halo wars 2 started automatically updating one day. It stopped at 44% and it would not go any further. I have 300gb of storage remaining. My Xbox suggested that I uninstall and reinstall. Upon doing that it told me that the game was corrupt. It’s still stops at 44%. All of my other games and functions work fine. Someone please help. Btw I have not downloaded the latest expansion so I don’t think it is directly related to that. Thanks for any help you can provide!

This is part of a known issue and has been investigated by 343 and escalated to the team at Xbox. Looks like Xbox have identified the issue and are working to fix, a dashboard update has been released to Insider Alpha and Beta ring users that should hopefully resolve this issue.
