Sci-Fi Free Marketplace Assett. Can anyone explain these errors? (Error: 0x887A0006 - 'HUNG')

I downloaded a really great asset pack, and when I go to run the level (all shaders have been built etc) it freezes in a few seconds.

1080Ti and i7 in UE 4.23.1

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: 0x887A0006 - ‘HUNG’)

try update your GPU driver

Hey @nichaohao thanks for the reply
I’m using Studio Driver 442.19, the latest. Any other ideas what I might try?

The error message doesn’t show any meaningful message. you can download a debugging symbols to see the actual error.
