Packaged Game Crash Only... Assertion Failed, GetRayTracing, SkeletalMesh... how to find the offending object? 4.27

When opening a specific level in the packaged game, the following error gets thrown up on level load:

Assertion failed: LODSection.SectionElements.Num() == MeshObject->GetRayTracingGeometry()->Initializer.Segments.Num() [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Engine/Private/SkeletalMesh.cpp] [Line: 5729]

In the editor, even running as standalone, the level is fine. The error seems to indicate that there may be a skeletal mesh with an issue… is there any way to get more information about exactly which mesh is causing a problem?

Thanks
