I'm trying to play CSGO with a friend, but whenever she joins the lobby, after a few seconds my game freezes, audio and all. If I click, the game just crashes, but if my friend leaves then the game resumes as normal. We were playing fine a week ago.
I googled it and other people have had similar problems, but not the same. Most had their game fully crash along with their steam client. They also couldn't find a solution other than some "Killer Network Driver" from their motherboard, but I have made no hardware or driver changes, and I've been using this motherboard for a few years now.
