Railsでアプリ作成中、突然HEROKUデプロイするとエラーが表示されるようになった

Question

前提・実現したいこと

HEROKUデプロイを実行するも、エラーが発生してしまい、困っています。
開発環境：ローカル（Windows10）
ruby 　2.4.5
Rails　 5.1.6

現在、Railsチュートリアルを終え、食べログのコピーサイトを作っているのですが、いままで問題なくできていたHEROKUデプロイが突然できなくなってしまいました
ローカル環境では、問題なく動く上、Githubへのプッシュはできています

エラー改善のために参考にしたQiita記事

remote:        HEADS UP! i18n 1.1 changed fallbacks to exclude default locale.

remote:
remote:        Please check your Rails app for 'config.i18n.fallbacks = true'.
remote:        If you're using I18n (>= 1.1.0) and Rails (< 5.2.2), this should be
remote:        'config.i18n.fallbacks = [I18n.default_locale]'.
remote:        If not, fallbacks will be broken in your app by I18n 1.1.x.

remote:        Thank you for installing fog!
remote:
remote:        IMPORTANT NOTICE:
remote:        If there's a metagem available for your cloud provider, e.g. `fog-aws`,
remote:        you should be using it instead of requiring the full fog collection to avoid
remote:        unnecessary dependencies.
remote:
remote:        'fog' should be required explicitly only if:
remote:        - The provider you use doesn't yet have a metagem available.
remote:        - You require Ruby 1.9.3 support.

自己解決しました。
ご覧頂いた皆様、ありがとうございました。

app>assets>stylesheetsに増やしたファイルを消したことで解消ができたようです。
無事HEROKUデプロイできました。
