Hi .

I’ve looked up your submitted crash report, and the issue you are experiencing is this:


Fatal error: [File:D:\Build\++UE4+Release-4.14+Compile\Sync\Engine\Source\Runtime\Windows\D3D11RHI\Private\D3D11Util.cpp] [Line: 176] Unreal Engine is exiting due to D3D device being lost. (Error: 0x887A0006 - 'HUNG')

Basically, the engine is crashing because the graphics card is taking too long to respond. This may be simply due to an inadequate or failing graphics card, but we are aware of an increase of these crashes occurring in the 4.14 release. See known reports:

The tickets may say they are “fixed”, but that’s not entirely accurate. We have fixed some confirmed causes of these crashes, but other causes are still occurring. We need help in identifying reproduction cases for these crashes, so we can experience them internally and resolve the issue. If you have any more information to share, please review and follow this guide to properly report the issue: Einen Fehler melden - Unreal Engine

Cheers
