This issue is very similar to MCPE-149193 except I am unable to load any of my worlds regardless of file size. This issue affected me on my ps5 and ps4
I have tested 10 different worlds every one of them had the same issue. Expected result. The world loads properly and is able to be played.  Current result. The world trys to load for 50 seconds then displays the attached screen shot. I have tried everything that I know to do. I have Uninstalled the game and cleared the cache. Update. I wouldn't say this issue is fully resolved however most of my world do work again! Large worlds are still giving me problems every now and then. Update2. This problem is still present  even after all this time. However, you can fix this issue (on windows) check the pinned comment. However, mojang should fix this for those who can't afford minecraft realms/don't want to pay to move there world to a pc to fix it. Or those of you that don't have a pc/laptop!
