i attach static meshes to actor at runtime from code using code from wiki

 AssetSM_StaticMesh =  LoadStaticMeshFromPath(FName(*ModelName));
    
    				StaticMesh = NewObject<UStaticMeshComponent>(this);
    
    				StaticMesh->SetStaticMesh(AssetSM_StaticMesh);
    				
   
    				StaticMesh->SetVisibility(true, true);
    
    	
    				StaticMesh->RegisterComponent();
    
    				StaticMesh->AttachTo(RootComponent);

but this freezes game at 1 - 2 seconds. mesh is very simple have 200 triangles and one simple material with base and normal textures their size 1024х1024.
