I have a 1.1GB world on ps5 bedrock Minecraft, whenever I load my world (and load around 15-20 chunks or so) and leave the world, after trying to immediately open the world again, I get hit with an error message stating "there was a problem loading this world" Mojang experts after troubleshooting have decided it is a bug. It always consistently happens on the same world, whenever I make any kind of progress, I then can no longer access the world after leaving. 

this is a bug that I have been trying to research for months now, no one else seems to have encountered it, the world data corrupts itself after leaving the world no matter what, every time, even whilst the game is kept running, I have found no solution at all.
