Crash at Skeleton Remapping

The details are in the EPS : [Link Removed]

For short, a Skeleton A_Skeleton mapping to B_Skeleton, and there are multiple SkeletalMeshes using the A_Skeleton,  SkeletalMesh_A has been loaded and is ticking animation on a worker thread, SkeletalMesh_B is loading on the Asyncloading thread, the RetargetingTable could be reset through (USkeletalMesh::Serialize -> GetRefSkeleton().RebuildRefSkeleton -> UE::Anim::FSkeletonRemappingRegistry::Get().RefreshMappings), and the RetargetingTable could be used in UE.Anim.Decompression.DecompressPose.
