Realmデータベースのアイテムを使用してRecyclerViewがクラッシュする

Question

私は、ゲームオブジェクトのリストを表示すると思われるフラグメントを持っています。フラグメントが始まると、データベースからすべてのゲームオブジェクトを読み込んでリストに追加します。それはリストのサイズが12に達するまでうまく動作します。そうであれば、フラグメントが表示される前でもアプリケーションがクラッシュします。リストが13より大きい場合は、すべてスクロールして下にあるゲームを試してみるとクラッシュするだけです。

これを引き起こす可能性のあるアイデアはありますか？私は本当にRecyclerViewが問題だとは思わない。 ここに私のクラスがあります。詳しい情報が必要な場合はお知らせください。

非常に助かります。
