Once I have connected to a game and then I tab out of the game it occasionally crashes really bad and my whole game freezes. After this, the game crashes. When I try to reconnect to my RANKED game it responds with 4-0xfff0bdc0. No matter how many times I restart the game after this point I cannot reconnect. This has happened multiple times leading to many cooldowns and rank drops. I would post this a support case but it is currently down.
