cannot use my model on my controller " Undefined type 'App\Usuario' " Laravel

Question

Hello I cannot use my model inside controller Undefined type 'App\Usuario' on Laravel.

When I try to, create, edit or remove an user I am getting error Undefined type 'App\Usuario' appears.

A few days ago the code worked for me but when I made another model called "paintings" they both stopped working. Maybe has some relation.

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

class Usuario extends Model
{

    use Notifiable;
    use HasFactory;

    // ...
}

namespace App\Http\Controllers;

use App\Usuario;
use Illuminate\Support\Facades\Validator;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\DB;

class UsuariosController extends Controller

{
    public function index()
    {
        $usuarios = DB::table('usuarios')
            ->select('usuarios.*')
            ->orderBy('id', 'DESC')
            ->get();
        return view('usuarios')->with('usuarios', $usuarios);
    }

    public function store(Request $request)
    {
        $id = 0;

        // Validation ...

            $usuario = Usuario::create([
                'id' => $request->id,
                'nombre' => $request->nombre,
                'email' => $request->email,
                'contrasena1' => Hash::make($request->contrasena1),
                'contrasena2' => $request->contrasena2,
            ]);
            return back()->with('UsuarioAgregado', 'Usuario agregado con éxito');
       
    }

    public function destroy($id)
    {
        $usuario = Usuario::find($id);
        $usuario->delete();
        return back()->with("El ususario se elimino correctamente");
    }

    public function editarUsuario(Request $request)
    {

        $usuario = Usuario::find($request->id);

        // Validation ...

            $usuario->nombre = $request->nombre;
            $usuario->email = $request->email;
            $validator2 = Validator::make($request->all(), [
                'contrasena1' => 'required|min:7|required_with::contrasena2|same:contrasena2',
                'contrasena2' => 'required|min:7'
            ]);
            if (!$validator2->fails()) {
                $usuario->contrasena1 = Hash::make($request->contrasena1);
            }

            $usuario->save();
            return back()->with("El usuario se actualizo correctamente");
        
    }
}

Sorry if my English is not good. [1]: https://i.stack.imgur.com/MCKnl.png

maybe you need to use this code on the header of your controller :

use App\Models\Usuario;

that's a common problem. it depends on the structure of your project's directory.
