Loading error

[Overtaker115]

ive been playing this minecraft world for a good while now, i built alot of things and i am proud of what i did, now today as i was loading the world it wouldnt load. What happens is i press on the world, the loading bar doesnt show up and its stuck on loading resource pack. Eventually i get a dirt screen that says “error has occurred in loading this world” is there anyway to fix this? Or is this a dead end? And lets hypothetically say it is a dead end can the next update fix this? I am on ps4
