Infinite white loading screen

I play on Xbox so no mods or anything. I finished building an apartment complex in Tomarang and when I try to go to the world I get an infinite white screen. I can go to any other world no problem. I can move my cursor around but if I do anything and I mean anything the game crashes. I didn’t save the building or anything in that world to gallery so I need it back please. Any suggestions or recommendations would be great.
