Corrupted World after Village and Pillage Update

Previously, there was a bug where if you tried to go to a world that took up more space than a set amount, it wouldn't open and you would get a message saying it was too big even though it isn't too big. After updating to Village and Pillage (1.14), it said they fixed this bug on minecraft.net. When I tried to open the world, it said it was corrupted. I play in vanilla with no resource packs and beta is disabled. Please help as I have a lot of progress in the world and I have worked hard to get to the level I am at right now
