Error: TokenMismatchException in VerifyCsrfToken.php line 67:

I'm trying to upload videos using laravel and I'm releasing that error, even putting the {!! csrf_field() !!} and {{ csrf_token() }} keeps throwing me the error, also deactivates in the kernel the \App\Http\Middleware\VerifyCsrfToken::class, , and here something curious happens too, in the form I have 2 validations required for 2 fields and when I send the form I get an error that those fields are required even when I fill them out.

If I remove the validation from required to these fields, it is the only form that is sent but to the BBDD nothing arrives, if someone knows how I can solve mainly the error of Token .
