As someone previously posted, you can load files by disconnecting your PS5 from the internet. A mindf@ck of a fix, but there it is. This game is turning out to be the next Cyberpunk 2077, the amount of issues in the PS5 port are staggering, crashes, doesn't load saves unless you disconnect your console from the internet, freezes if you summon, textures don't load in Act 3, crashes when in multiplayer, frame rate below 20s in Act 3, the list goes on. And they're extra deceptive as most of these issues don't present themselves far later in the game.
