So I've had this minecraft world for a while. A couple months back when I tried to join it said there was a problem loading this world. Ever since then I was unable to join it I I tried everything but nothing worked

My minecraft world was very good me and my friend had a lot of farms and we even dug out a chunk to bedrock. I even found out a duplicate glitch that I used. But a couple months ago I was unable to join. If I try to make a copy of the world a blank and purple pattern comes up the my game crashes. I play on minecraft PS4 bedrock.
