Hello. Today when I started minecraft (windows 10 edition) I started playing in my world after a few minutes my minecraft fell. (Black screen) When I later turned minecraft again my world disappeared I found it even in game files. I've been playing the world for a long time, I've always been putting myself right, but today, unfortunately, not. Can you advice how to get the world back or how to avoid this? Thank you for your response. (I'm writing this on google translators) can you help me?
