Just a bit of potentially helpful info here. I was having the exact same issue as OP. Menu was blank except for server names and if i tried to join a server, my game would crash completely. after doing some process of elimination troubleshooting, I restored Windows to a fresh install but kept all my files intact. I also updated my BIOS to the latest release. I re-downloaded Steam, Re-installed the latest driver for my GTX1070 and made sure i installed every windows update package they had for me. when it came time to re-install DayZ, I instead installed it on my C drive SSD that has windows on it. Before i restored windows and i was having all these issues, DayZ had been installed on my HDD where i usually install all my games. everything runs flawlessly now. not a single crash and the UI is back to normal. Im back in Chernarus.

same exact issue here. also game will crash every time after about 3min of navigating this menu with no words
