Hi I'm a Xbox One player and I'm having frequent problems with Minecraft. When I open some of my world, it appears: "It was not possible to load your world" and then I click again and nothing happens and I can't enter any of my worlds, I've restarted, I've uninstalled and installed it again and nothing. I test now if it's open and the same thing is happening.

This is really upsets me because I love to play and besides that sometimes I can enter in my world and then suddenly turn everything off. I will be very happy if you could help me please, thanks
