I had a world that me and my friends worked on it. Yesterday I brought my xbox 1 over to a friends house and tried to load the world. It glitched and sent me back to the home screen, now it's gone, I need someone to explain it further To. Please help.

It's been the most fun I've had in a long time. Yesterday I brought my xbox 1 over to a friends house and tried to load the world. It was in the middle of loading when it sent me back to the home screen of my xbox before loading. When I went back on the world was gone. There was a different "new world" in its place. I did nothing to delete or reset the world. I tried to check storage and I couldn't find it. But when I went on my friends Xbox and logged into his it was there. But when trying to load in it said "failed to sync world data" and suggest I go on a console in good state. I then tried it on my brothers xbox one and it said the same thing. I've never had a Minecraft world that's been this fun and I've been playing for like 6 years now. It would mean the world if someone could help me get my world back, I have a feeling someone will see this and help... please
