In my case the PS5 menu would open properly, but yes, everything else was slideshow slow. Since the PS5 has its own dedicated memory, it could either be a memory leak or a massive server slowdown, however I fail to see how a server issue could crash my game. In every single online game i've ever played, a server issue or lag spike usually presents itself with others seemingly lagging, even if its you the one experiencing issues. There's probably a combination of actions that just triggers the game into imploding lol.
