Nightmare Before Christmas Map keeps crashing! 😡

I’m frustrated to death. I have this awesome map of The Nightmare Before Christmas, and the skins work fine and everything (as far as I know), but the map itself with all the iconic imagery, works about as well as jamming a fork in an electrical socket. Every time I play for a little bit, I get this stupid message that says “Disconnected due to world corruption Try reopening the world or restoring it from a previous backup” on a gigas reminiscent screen. Happens every single time I try to use this map. Other times it just outright refuses to open the map. There are no corrupted files in my saved data and I just got the thing yesterday so obviously I don’t have it backed up. Reopening it doesn’t work. This is a big big disappointment to me, I wanted to explore through this world and maybe even expand on it as I am a huge Nightmare Before Christmas fan. What is the possibility of fixing this? Also, it should be noted that I am updated to the most recent version of Minecraft for PlayStation 4 in 2020. I would like and greatly appreciate some assistance, thank you.
