Playstation: Game freezes, massive lag spikes, infinite loading screens, no texttures

The game freezes and lags every map, specially when there's a lot of monsters.
It's unplayable right now and very frustrating.
Tried legion 5-way with a friend and we both had to restart 4 times.
Either you disconnect and drop back to the menu or the game freezes completely and you have to restart.

Edit:
Just did The Maven using all portals and failed.
Textures were not loading.
- Couldn't see the purple flash of the memory game = dead
- Couldn't see the platform when the brain was spawning = dead
- Couldn't see rotating beams of the brain in last phase = dead
- Couldn't see degens on the ground = dead

Everytime I died and was about to go back to hideout the game froze during loading = closing the game.
One time I was loading in the arena, heared maven speak and using her skills but was stuck in infinite loading screen.

Failed without a fair chance. Thanks for nothing. Is this a joke?
