SQLSTATE [42000] (Mysql 8.0)

Bonjour,

Voila je rencontre un petit problème avec mon code.

Ce que je fais

J'ai une liste d'utilisateur que j'affiche dans un tableau. Lorsque je veux éditer un utilisateur, catastrophe. Plus rien ne marche.
J'ai cette erreur qui me fatigue la vue... et je crie à l'aide :(

// Extrait du tableau

                            <td scope="col">
                                <div class="dropdown pull-xs-right m-l-1">
                                    <button type="button" class="btn btn-xs btn-outline btn-outline-colorless dropdown-toggle" data-toggle="dropdown" aria-expanded="false"><i class="fa fa-cog"></i></button>
                                    <div class="dropdown-menu dropdown-menu-right">
                                        <li><a href="?page=admin.edit&id=<?=$user->id?>"><i class="dropdown-icon fa fa-pencil"></i>&nbsp;&nbsp;Editer</a></li>
                                        <li><a href="#"><i class="dropdown-icon fa fa-times text-danger"></i>&nbsp;&nbsp;Remove</a></li>
                                    </div>
                                </div>
                            </td>

// edit.php

$app = App::getInstance();
$userTable = $app->getTable('user');
$user = $userTable->find($_GET['id']);

// Ma function dans userTable.php

    public function find($id)
    {
        return $this->db->query("SELECT * FROM {$this->table} where matricule=?", [$id], true);
    }

// MysqlDatabase.php

<?php

            $data = $req->fetch();
        } else {
            $data = $req->fetchAll();
        }
        return $data;
    }

    public function prepare($statement, $attributes, $class_name = null, $one = false)
    {
        $req = $this->getPDO()->prepare($statement);
        $res = $req->execute($attributes);
        if (

        } else {
            $req->setFetchMode(PDO::FETCH_CLASS, $class_name);
        }
        if ($one) {
            $data = $req->fetch();
        } else {
            $data = $req->fetchAll();
        }
        return $data;
    }
