Unity2D - Why are sprites not displayed when starting a project?

Question

Unity

I recently started learning Unity3D, doing my first project, and when I started lvl, I found that sprites are not displayed on some of them. What could be causing this, and how can I fix it? Happy in advance for help. Here are screenshots: https://imgur.com/a/znZdZHX

Answer 1

Is it displayed in the editor in the game tab? If not, then the camera is probably too close. Then you need to move it or the sprite in z so that the sprite falls into the camera's field of view.

Answer 2

Layer, z position - check these things first
