I was basically done with the first mission, when my game suddenly started to studder, it slowly got worse until it froze. My game was frozen for a good minute before it crashed. Now the game won't load past the initial Destiny 2 screen. Now, after 20 - 25 times of trying to load the game it gave me the error code buffalo after saying, You must restart your game through the Battle.net client. Each time I have loaded it through the Battle.net client and it hasn't worked before the error, or since.
Edit2:
I just recently tried to restart the game and got error code chicken.
