Good day,

First thank you for the great game, appreciate your work,

My problem is that (after 60 hours) the game started insta-crashing whenever I try to launch it, without even loading the main menu. Fatal Error message screenshot  CoreTech 2 fatal error (Text version if link doesn't work: Fatal error at ..\..\src\Graphics\API\Device_DX11.cpp(8065): Error when loading texture: C:\SteamLibrary\steamapps\common\Warhammer 40,000 Inquisitor - Martyr\UI\LoadingScreens\Inital.dds

I've already validated the files through Steam 3 times (says one file didn't pass the check and will be downloaded again, but game still crashes) and installed everything from InstallUtils folder. I've also tried reverting to previous graphics driver with clean uninstall in safe mode. I've disabled all background programmes like Nvidia game overlay, Nvidia Ansel, etc.

I suspect it's somehow connected to DirectX and maybe recent Windows 8.1 system updates as Halo Master Chief Collection (uses Unreal Engine) also started to insta-crash, error - LowLevelFatalError D3D device being lost (Error 0x887A0020 - 'INTERNAL ERROR') Other games, like CS:GO works fine.  I know that I cannot update DirectX 11 manually as its updates only come with system updates. I also know that certain Windows 7 system updates like KB3080149 and KB2670838 fixed D3D fatal error in the past. 

The game is on SSD, has latest patch

Windows 8.1 with latest updates

Intel i5 4200h with Intel HD Graphics 4600

12 GB RAM

Geforce GTX 850m  with latest driver (451.67 - 27.21.14.5167)

Thank you in advance and sorry for TL/DR
