Whenever I open up one of my worlds in my game, the game crashes 2-3 times within seconds of opening before it becomes playable

Whenever I open up a specific world it lags and then crashes 2-3 times before it becomes playable. Any items in my inventory that were recently acquired and any mounts I'm riding completely disappear from the world. I'm not doing anything crazy like having a bunch of mobs in a small area or anything else that would make the game crash. I've just been playing normally
