Please try to switch between DX9 and DX11 also, maybe that helps.
Also make sure that there is no injection conflict with some other program on your PC. Start crashes often are related to other programs also hooking into a game like vorpX, which can cause all sorts of issues.
Hottest candidates are: virus scanners, any sort of CPU/GPU utilities, game video recording/streaming software, chat programs and generally everything that can show notifictations in games.
Best way to trouble shoot is to disable/uninstall every program running in the background that would not be there after a fresh, Microsoft only Windows install.
