消去 signing-config.json から \app\build\intermediates\signing_config\debug\out それで File->invalidateキャッシュと再起動。これは私のために働いた。

Neact-Native-Firebaseを使用していますか？これを使用してインストールした場合は、これと同じ正確な問題がありました。

yarn add @react-native-firebase/app _

アンインストールしてみてください。

yarn remove @react-native-firebase/app _

そしてインストールを使用する

yarn add react-native-firebase _

編集：

その後、この問題に遭遇する可能性があります。

クラスパスバージョンを一度ダウングレードしてみてください
