Model doesn't pass data to view

Hello everyone,

I've a stupid issue and I'm crazing.

I've a Model:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Campionato extends Model
{
    use HasFactory;

    protected $table = 'campionati';
}

Controller:

<?php

namespace App\Http\Controllers;

use App\Models\Campionato;
use Illuminate\Contracts\View\View;
use Illuminate\Http\Request;

class CampionatoController extends Controller
{
    /**
     * Display a listing of the resource.
     */
    public function index()
    {
        $campionati = Campionato::all();

        return view('campionati.index', compact('campionati'));
    }

    /**
     * Display the specified resource.
     */
    public function show(Campionato $campionato)
    {
        return dd($campionato);
    }

    /**
     * Show the form for editing the specified resource.
     */
    public function edit(Campionato $campionato) :View
    {
        return dd($campionato);
    }
}

Route:

Route::get('/', function () {
    return view('welcome');
});

Route::get('/dashboard', function () {
    return view('dashboard');
})->middleware(['auth', 'verified'])->name('dashboard');

Route::middleware('auth')->group(function () {
    Route::get('/profile', [ProfileController::class, 'edit'])->name('profile.edit');
    Route::patch('/profile', [ProfileController::class, 'update'])->name('profile.update');
    Route::delete('/profile', [ProfileController::class, 'destroy'])->name('profile.destroy');

    Route::resource('campionati', CampionatoController::class);
});

require __DIR__.'/auth.php';

The index works fine, but when I open the "edit" or the "show" I see:

App\Models\Campionato {#1304 ▼ // app/Http/Controllers/CampionatoController.php:50
  #connection: null
  #table: "campionati"
  #primaryKey: "id"
  #keyType: "int"
  +incrementing: true
  #with: []
  #withCount: []
  +preventsLazyLoading: false
  #perPage: 15
  +exists: false
  +wasRecentlyCreated: false
  #escapeWhenCastingToString: false

  #touches: []
  +timestamps: true
  +usesUniqueIds: false
  #hidden: []
  #visible: []
  #fillable: []
  #guarded: array:1 [▶]
}

So I've not data. The data is null.

I created a new project for testing. I started from scratch, thinking I was making a stupid mistake, I followed an elementary CRUD tutorial, but nothing.

Where am I doing wrong?
