Hi I’m saving the modified skeleton mesh at the runtime. It goes well during saving the package but that error is occurred and that error is related to the ~FDuplicatedVerticesBuffer(). How can I solve this error?

Here is the code, log output and call stack:
code:

void FPersonaMeshDetails::UpdateMeshAsset(USkeletalMesh* TargetMesh, FString PackagePath)
{
	FString DestRelFilename = FPackageName::LongPackageNameToFilename(PackagePath, ".uasset");
	FString DestAbsFilename = FPaths::ConvertRelativePathToFull(DestRelFilename);
	FPaths::MakePlatformFilename(DestAbsFilename);

	TargetMesh->GetResourceForRendering()->ReleaseResources();
	TargetMesh->FlushRenderState();
	TargetMesh->ReleaseResources();

	TargetMesh->PostInitProperties();
	TargetMesh->PostEditUndo();
	TargetMesh->MarkPackageDirty();
	
	UPackage::Save(TargetMesh->GetOutermost(),nullptr,RF_Standalone,*DestRelFilename);
}

Log output:
