rails sで大量のエラー。先ほどまで問題なく動いていました。

Question

前提

Rails5.2
Windows + Vagrant

内容

Railsを開発で動作させている最中に、OS（Windows）が自動で再起動されてしまいました。
その後、rails sをすると、エラーが表示されるようになりました。先ほどまで問題なく動いていてにも関わらずです。OSを再起動しても、元に戻らない状態です。何が原因だと思われますでしょうか。

$ rails s
=> Booting Puma
=> Rails 5.2.8.1 application starting in development
=> Run `rails server -h` for more startup options

まずはエラーメッセージをご自身で調べてみたほうがよいかと思います。
4〜5行目の「Run `rails server -h` for more startup options Exiting」とかで検索してみてはいかがでしょうか？

はい、やってみます。

直前に修正したコードをコメントして、rails sをすると正常動作しました。
コントローラーに１つメソッドを追加して、routes.rbに、メソッド用のルートを１つ追加しただけです。
正常動作した後、コメントを外しても、エラーが再発することはありませんでした。
原因は不明ですが、とりあえず、自己解決しました。
