Unreal Engine 4.18.3 crashing

Unreal Engine 4.18.3 keep crashing when I open it.
How to fix it ?
Any idea ?
Thanks in advance.

Hey there, install the debug symbols to be able to see where it crashes inside the engine, then send a screenshot of it.

The bottom half of the Crash window contains a link to the folder where the crash log files are stored. Can you share here or via Pastebin the one with the .log extension? That will help us understand what is wrong and offer some more suggestions.

Fatal error: [File:D:\Build++UE4+Release-4.18+Compile\Sync\Engine\Source\Runtime\Windows\D3D11RHI\Private\D3D11Util.cpp] [Line: 182] Unreal Engine is exiting due to D3D device being lost. (Error: 0x887A0005 - ‘REMOVED’)

It’s a crash of the graphic card and Windows TDR tries to restore it by removing and re-adding the device. This makes UE4 crash because it loses access to the graphic card.

I had it as well for some time, here the most common causes I found:

A corrupted Graphic Card Device Driver

A conflict with other applications also using DirectX

CPU and GPU overclocking

Try the following for each issue:

  1. Download DDU (Device Driver Uninstaller) and do a clean uninstall of your Graphic Card drivers. Then reinstall them. Check again if UE4 is crashing.

  2. With the Task Manager, stop all applications you suspect may be interfering with DirectX. Anything that records the screen (including NVidia’s own screen capture) or that improves the frame rate. Check again if UE4 is crashing.

  3. Temporarily turn-off any CPU/GPU overclocking. Check again if UE4 is crashing.

This should help you determine where the problem could be, but this is one of the trickiest errors to get, believe me.
