Quote from the licensee
(FbxSkeletalMeshImport.cpp inside "// merge bones to the selected skeleton"): this happens because in UnFbx::FFbxImporter::SetupAnimationDataFromMesh, the function FindFBXMeshesByBone returns a nullptr but nothing checks for it, so RecursiveBuildSkeleton and IsUnrealBone will use a nullptr.
Reimport a skeletal mesh with some change in the skeleton
RESULT
Editor can crash depending on the skeleton change
EXPECTED
Editor handle nicely the case and do not crash
