Unreal 4 Editor 4.23.1 crashes.

Permanent crashes. Use Windows 10 64bit.
Error message:

assertion failed: [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Windows/D3D11RHI/Private/D3D11Util.cpp] [Line: 198] Unreal Engine is exiting due to D3D device being lost. (Error: 0x887A0005 - ‘REMOVED’)

What can I do? thanks for your help

You have luck. In my case the hole system crashes. No error messages, no bluescreen reports or so.

ich habe den Grafikkartentreiber neu installiert, dach war wieder alles ok.
