Launch failed

Basically I tried to update one of my worlds to 1.18 and it isnt loading anymore, I cant edit it or play it, when I try it says launcher failed. I have never had issues and can update all the other worlds just fine. It just this one. I would hope there is some kind of fix as this is one of my bjest worlds. It is a 953.1 MB and storage shouldn't be an issue. If there is a fix please let me know.
