How to fix this? Beginner needs help

I am a complete beginner and I am just getting acquainted with unity. in game mode I was checking the functionality of interactivity with items and decided to see if there would be a bug. by pressing F twice I paused the game mode and the scene window appeared with this interface (see the first screenshot), although during the game everything is visible (see the last screenshot). please tell me how to return the previous view of the scene window.

in bottom picture there are tabs “Scene, Game, Animator” click on Scene ( I think it is)

It looks like you probably zoomed out too far. To fix this just select a game object in your hierarchy and double-press f to focus in on it.
