My top view doesn't work although other views work

Hi! I want to ask about view! When I turn on my Rhino, sunddenly my top view doesn’t work. My model is disappeared and I can’t draw anything in top view. so I tried several ways like two times of 4view to reset my view, finding some strange line which can interrupt camera and finding clipping plane. but They didn’t work. so may I ask what is problem and how to solve this problem? please tell me detail of solution when you explain me. because I’m not good at using rhino.

Hello - most likely you have an object very far away. Select all the visible objects with a window selection(s) and then Invert is anything selected?

I did your solution now. but it doesn’t work. Invert is anything selected.

Hello- try, from the context menu, closing the viewport-

] then then run 4View. If that does not sort it out, please run SystemInfo in Rhino, copy/paste the results here and either post your file or send to tech@mcneel.com, with a link back here in your comments.
