You can move your cloud saves to local saves in the screen to select your character and world, both have an option for managing saves. Problem is, just like you, I reload the game and it's crashing within seconds after the first crash that happened out of no where. (Not even using cloud save)

It's not good and I have also experienced this more than once.
