how can i host a server?

нажимаю play и выбираю сервер и вроде всё хорошо но потом пишет неизвестная ошибка

Is there a way to fix this? I can play on mouse and keyboard fine, but when I hit one button on the controller, the game has a fatal error and crashes?

I don't know what is going on but i can only play practice and any server i join it will load then quit the game and give me a error and say connection lost please help

^^ As the title says. A friend tried to launch this and told me they were unable to play the game with the exception of practice mode and I can confirm that this is the only mode available at the moment. Also my performance has decreased a lot since that last patch...
