they rolled back the game to a previous, stable version on ps4 but you have to delete and reinstall it entirely. they're working on a better overall fix in the mean time but you will lose any progress you made as a heads up. i've done this myself and been playing the rolled back version and can confirm it works. 

I got both digital and physical release for this collector editions and everything I own the signature edition of dungeon of the endless I have high Hope's for the game but for some reason since the first patch game is literally unplayable I can only get a few combats in before crashing often on the first combat I've tried everything please fix the game
