Help needed. Freeze frame when in play mode

Hi!
I'm absolutely new to Udemy, doing the course on the website. Just made my first scene but when I press on a play button to move to a game mode - the scene doesn't move at all. It simply doesn't respond to the buttons. Any ideas what am I doing wrong?

 

Are you receiving any errors? Maybe sharing a screenshot of the entire Unity window would help see what your situation is.

 

no error on the screen, it's just frozen

 

no errors in the console either

 

You'll probably have to share the code you're running, then. Specifically, anything that's supposed to be handling the input that isn't being responded to.
