Php versions – Why laravel validation don't displaying errors

I’m trying to validate a request from form and appear a problem, not showing error messages on the view.
The validation succeeds, refreshing the view but not displaying errors. Apparently $errors is always empty
I tested it on fresh installation.

Laravel Version: 5.8.33
PHP Version: 7.3.8
Database Driver & Version: mysql 5.7.22

Form is this

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

    <form class="form-group" method="POST" action="/trainers" enctype="multipart/form-data">
        @csrf   

        <div class="form-group">
            <label for="">Nombre</label>
            <input type="text" name="name" value="@isset($trainer->name){{$trainer->name}}@endisset" class="form-control">
        </div>

        <div class="form-group">
            <label for="">Slug</label>
            <input type="text" name="slug" value="@isset($trainer->slug){{$trainer->slug}}@endisset" class="form-control">
        </div>

        <div class="form-group">
            <label for="">Descripción</label>
            <input type="text" name="description" value="@isset($trainer->description){{$trainer->description}}@endisset" class="form-control">
        </div>

        <div class="form-group">
            <label for="">Avatar</label>
            <input type="file" name="avatar">
        </div>

        <button type="submit" class="btn btn-primary">Guardar</button>
        </form>
@endsection

The store function with validation is this

public function store(Request $request)
    {
        $validatedData = $request->validate([
            'name' => 'required|max: 10',
            'avatar' => 'required|image',
            'slug' => 'required',
            'description' => 'required',
        ]);

        $trainer = new Trainer();
        $file = $request->file('avatar');

        if ($file != "") {
            $name = time().$file->getClientOriginalName();
            $file->move(public_path().'/images/', $name);
            }
            else{
                $name = "Sin Imagen.jpg";
                }
        // return $name; //Ver nombre archivo
        $trainer->name = $request->input('name');
        $trainer->avatar = $name;
        $trainer->description = $request->input('description');
        $trainer->slug = $request->input('slug');
        $trainer->save();

        return 'Saved';
    }

UPDATE
Add {{ $errors }} in blade and return [], $errors is empty

    It's strange but solve the problem by changing local server. I used XAMPP and now I use MAMP and everything works perfect. If you are working locally with Laravel I recommend not using XAMPP.

    try this

    @if(session('success_message'))
            <div class="alert alert-success alert-dismissible" role="alert">
              <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span> </button>
              <strong>Successful!</strong> {{ session('success_message') }}</div>
            @endif
            @if(session('error_message'))
            <div class="alert alert-danger alert-dismissible" role="alert">
              <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span> </button>
              <strong>Error!</strong> {{ session('error_message') }}</div>
            @endif

    Instead of using $request->validate
    edit your code and Use $this->validateor this code instead: 

    $messages = [
              'description.required' => 'description is required',
       ];
        $validator = Validator::make($request->all(), [
            'name' => 'required|max: 10',
            'avatar' => 'required|image',
            'slug' => 'required',
            'description' => 'required',
        ],$messages);

    should add to method withError()
    As above 

    if ($validator->fails())
{
   return redirect()
    ->back()
    ->withErrors($validator)
    ->withInput();
}

    if page refresh means error object not empty…and your validation code in controller work so check html code with inspect element in browser.maybe error box is hidden or for test it you can use this code in your blade

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

    I hope this will help you 

$validator = Validator::make($request->all(), [
    'amount' => 'required|amount|numeric|min:25'
])->validate();

if (isset($validator) && $validator->fails()) {
    return redirect()->route('investment')
        ->withErrors($validator)
        ->withInput();
}

in your blade file add below code
@if (count($errors) > 0)
<div class = "alert alert-danger">
  <ul>
     @foreach ($errors->all() as $error)
        <li>{{ $error }}</li>
     @endforeach
  </ul>
 </div>
@endif
