issues loading a world

Since the cliffs and caves update a world i had created began to crash and boot me as well as the rest of my members off saying storage was full even though it wasnt in game or on my ps4. Then all of a sudden the world wont load and keeps saying there is a problem loading the world. i have tried to uninstall and reinstall minecraft and it still wont work. Im not sure if there is a way to view the issue or correct or restore it. i play with about 6 other people and we play every night, we have alot of time, effort and love into the world and were all really upset. i hope there is a way it can be restored or rectified. we were hoping it would be sorted out with a new update but as 1.17.2 just dropped i am still have the same issue. thank you for your time.
