rails s でサーバーが起動しない

Question

Rails sでサーバを起動する方法が知りたいです。
エラーが出てしまい、動けなくなってしまいました。

Rails で簡単な勤怠管理アプリを作っていますが、
中々以下のエラーから抜け出せません。

=> Rails 5.1.6.1 application starting in development
=> Run `rails server -h` for more startup options

ソースコード

試したこと

エラー文を検索にかけ、
https://qiita.com/244mix/items/d74c10e1496811a19d2b
の記事を参考に対処しましたが、変わらずエラーを出しています。

補足情報（FW/ツールのバージョンなど）

ruby 2.4.5p335
Rails 5.2.2
sqlite は3.26.0
以上のバージョンをインストールして開発に当たっています。

C:/Users/user1/Desktop/kintai/config/environments/development.rb:43:in block in <top (required)>': undefined local variable or method tru' for #Kintai::Application:0x0000000006d08f30 (NameError)

にある通り、config/environments/development.rbの43行目でtruという意図しない文字列を使用していませんか？

ご回答ありがとうございます。
こちら、trueに直して起動をかけてみましたが駄目でした。。。

[sakas1231]

`Did you mean try?`と言われていますがその部分は本当にtrueで正しいのでしょうか？(config/environments/development.rbを見せていただければわかる気がしますが)
また、新たに出たエラーメッセージはなんでしょうか？
一つづつエラーを潰しきましょうb
