What is the reason for the infinite re-rendering of the component?

Question

JavaScript

Hello.
I will be grateful for help. I've been sitting on this problem for a long time. As a matter of fact I do simple check of fields (validation).
I can't figure out why I'm calling the useEffect hook (I'm guessing) an infinite number of times.

I will be grateful for your help!
