Why are the animation buttons disabled?

Question

Unity

Good afternoon, I ran into a problem, the solution of which I did not google.
In my Animation window, all the buttons are inactive except for "|<< |< >| >>|", in general, I can neither record the animation nor correct the existing one.

This state is always, that is, even when you select an animation, when you create an animation file, and when you simply open the animator without selecting an object, always
Tell me what to do?
