my world is corrupting randomly or just having a problem loading it up

hey, i’m currently on 1.14.41 on ps4. so i’m having this issue everytime i load up my world in ps4 after a good 3-5mins the game gives me a “disconnected due to world corruption” “try reopening the world or restoring it from a previous backup.” 

which i’ve done a previous backup and still have that same error. 

i’ve reinstalled minecraft and downloaded the previous back ups of the world. and still have this issue. 

also i get the purple and black block or menu screens after it kicks me out.

is there anything i can do? i’ve put so much work into this world, and i’ll be so devastated if I had to delete this world.
