Railsで action_dispatch/journey/formatter.rb `generate': No route matches エラー

Question

いつもお世話になります。

現在Railsでサイト作成しております。production環境でサーバーを
rails server --environment production
で立て運用していたのですが、一度ctrl+Cでサーバーを止めた後もう一度
rails server --environment productionした際に下記エラーが突如発生し、サーバーが立ち上がらない状態です。

/home/rails/xxx/vendor/bundle/ruby/2.3.0/gems/actionpack-5.1.4/lib/action_dispatch/journey/formatter.rb:55:in `generate': No route matches {} (ActionView::Template::Error)

どういったことが考えられますでしょうか。
ご教示いただけますと幸いです。
よろしくお願いいたします。

$ rails server --environment production
=> Booting Puma
=> Rails 5.1.4 application starting in production
=> Run `rails server -h` for more startup options

おそらくuserのところで引っかかっているので、userのコントローラーとViewのソースコードも共有してくれると助かります。

ご回答ありがとうございます。御教示いただいたとおり、users_controller.rbのメソッド外部分にrenderの文字が記載されているのが原因でした。その一行を消した所動作いたしました。簡単なお話でお恥ずかしい限りです。本当にありがとうございました。
