Doesnt Load

Upon turning on experimental game-play, it made a copy of my world. When trying to delete the extra world, It said "syncing worlds". After letting it sync for about 10 minutes, I restarted minecraft and it wouldn't even let me see my world because all it said was "Syncing Worlds". At this point it's been syncing worlds for 5 minutes each and I've restarted minecraft 10+ times. I've lost bout 900+ hours of work. Keep in mind I've only ever created 3 worlds and don't know what other worlds it's syncing to. Also yes I've restarted my console 5 times now.
