No solution here either but I have also encountered this issue today.
Initially a teammate had added the Volumetric cloud object to a map, and upon loading this map on my computer, my engine would crash with these errors
Fatal error: [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/RenderCore/Private/RenderingThread.cpp] [Line: 902]

The same crash and error is also given when I add a volumetric cloud to a map and play it.
