World not loading

This is my first post here so I might be doing things wrong, but my city world on my Xbox one will not load. I tried resetting my xbox, deleting the game, everything. nothing works. When I click on the world it says "generating world" then it freezes up. it has done this for a week now. the world is 2 years old, and my friends and I have been putting so much work into it I would hate to lose it. please help. this started after the 1.9 update. I tried getting the beta and opening the world but it does the same thing
