There is currently a known error with the latest PTR build where players who use the WoW.exe file to launch straight into the game will experience a crash. Since we are not planning to push any new builds for the remainder of this week, please ensure that you are launching the PTR using the World of Warcraft Public Test Launcher.exe file. We plan to addressed this issue in a future build.
