As shown in the image, this issue occurs when I import the model at runtime.
Could this issue be resolved? If so, how can it be fixed?

UStaticMesh::FBuildMeshDescriptionsParams MeshDescriptionsParams;
MeshDescriptionsParams.bFastBuild = true;
// Build static mesh
TArray<const FMeshDescription*> MeshDescriptions;
MeshDescriptions.Emplace(&MeshDescription->GetMeshDescription());

// At least one material must be added
StaticMesh = NewObject<UStaticMesh>(this);
StaticMesh->GetStaticMaterials().Add(FStaticMaterial());

StaticMesh->BuildFromMeshDescriptions(MeshDescriptions, MeshDescriptionsParams);
