would Unity disable gameobject temporary and automatically when loading a big assetbundle?

I have observed somet$$anonymous$$ng strange i added 2 print in OnDisable and OnEnable in a gameobject obj1 private void OnDisable() {

             print("test1");
         }
 
         private void OnEnable()
         {
             print("test2");
         }

then load an gameobject obj2 from a assetbundle, somet$$anonymous$$ng like t$$anonymous$$s

 LoadedAssetBundle ab = AssetBundleManager.GetLoadedAssetBundle(assetBundleName, out e);

without modifying anyt$$anonymous$$ng except the target object I load, somet$$anonymous$$ngs went weird, when obj2 is small, there is no "test1" neither "test2" appear in console. but when obj2 is big, w$$anonymous$$ch means I can see an obvious freeze, then "test1" both "test2" appear in console. W$$anonymous$$ch leader me to conclude the title. but I still doubt it, so I put a question here.
