Blade don't show validation errors

[Aibat1997]

After validation errors are not displayed in my blade. I use laravel v10.41.0
When I dump $erros variable it shows errors, but when I use it as in documentation, errors not showing

@if ($errors->any())
    <div class="alert alert-danger">
        <ul>
            @foreach ($errors->all() as $error)
                <li>{{ $error }}</li>
            @endforeach
        </ul>
    </div>
@endif
