Enemy attacks not rendering, Stuck in trial of sekhemas after failing.

I was just in a savanna map and it was running horribly, stuttering and terrible frame rates. When I got to the boss "Rathbreaker" I immediately died because the attack where all the giant spears come down from the cliffs were completely INVISIBLE. The attack didn't render or load until AFTER I was dead. This is not the first time something like this has happened, there are many attacks that do not render correctly and sometimes are completely invisible altogether. I love this game so far but it is horribly optimized. The devs said they created the game with controller in mind but it couldn't be more obvious that statement is definitely not correct. Another bug that is STILL prevalent is getting stuck in the trial of sekhemas after failing. You get a failed screen without an option to respawn or anything, in order to get passed this screen you have to completely reset your game. I have seen this bug reported multiple times. Something like that should be top priority. It hinders the ability to continue playing the game.
