UnityでつくったゲームをAndroidStudioでビルドした際に上記のようなエラーが発生したのですがどのように解決したらよいですか？

他にエラーが無いか確認してください。
（Consoleウィンドウから確認できます）

Answer 1

Unityのバージョンはいくつですか？
こちらやこちらによると、2019.3.0a1でのみ発生するバグだそうなので、その場合はバージョンを下げると直るかもしれません。
バージョン名に「a」が付いているものはアルファ版らしいので、「f」が付いているバージョンを使うことをおすすめします。

2019.3.0a5から2019.1.5f1に変更した結果、上記のようなエラー内容に変わりました。
