Why is the body of the POST request displayed in laravel when logging in and authorization is extinguished?

Question

Laravel

Hello guys, can anyone tell me - when I log in, it started to come out like this:

(always at the end and even after dd('') )

_token=***&email=***&password=***

At the same time, within the login, I can count data with Auth()->user()

But after the end of the controller action Auth()->user()is empty again.

What can be funny?
