It's a Windows 10 update that causes the problem--on the older build and the beta, too. That's why DynaHUD is now off by default. Better to make people turn it on and realize the consequences than just have what seems to be an inexplicable crash to desktop. I just hope they find a permanent fix quickly--I miss my DynaHUD. The standard HUD is pretty bad by comparison (for what I am interested in seeing and doing with a HUD).
