About 3 months ago (may 3rd 2021) When I tried to join my minecraft world it said there was a problem loading this world. I have tried a lot of things to fix it and still up to date it says the same thing. I have done many things in that world like building various farms and I even dog a 16x16 area from the surface down to bedrock. I play on PlayStation bedrock edition. Also when I try to make a copy of the world and I try to join in the black and purple checkered pattern will pop up then my game will crash Please help me get this world back it has help me get through tough times ( I will put a picture of what the black and purple checkered pattern looks like)
