Here you go, the broken model is HS510C red dot sight.

Currently, my only TEMPORARY solution to this issue is by re-installing the blender source tools. It worked fine only at first, but after I open it the second time, it goes back to being broken again.

If anyone want to get my model files, I can send it to you.
