[com.mcdonalds.mobileapp] npe becuase appUrl dont exists on com.google.firebase.dynamiclinks.internal.DynamicLinkData.deepLink

スタックトレースで特定された FireBaseDynamicLink$2.onSuccess コールバックから開始し、DynamicLinkData.deepLink と appUrl クエリパラメータがどのように処理されているかを調べます。報告された設定で Android 11 上の起動時クラッシュを再現します。appUrl がない場合にアプリがクラッシュしなくなれば完了です。
