本来、質問をする際はエラー部分の抜粋を試みるべきではあるですが、駆け出しのため、抜粋部分に誤りがあってはならないと思い、みづらく申し訳ないのですが、全文記載となります。

自分で試したこと
ここに問題・エラーに対して試したことを記載してください。
rails sが起動しない際の解決方法として以下のサイトを参考に対処を試みました。
上記のサイトではrails s が既に実行している際の対処方法が記されていたのですが、ｐｓコマンドを入力しても該当するものが見当たりませんでした。
使用ｐｃはM1マック
ruby,railsのバージョンは
four@FouRnoMac-mini testapp % ruby -v
ruby 2.6.9p207 (2021-11-24 revision 67954) [x86_64-darwin20]
four@FouRnoMac-mini testapp % rails -v
Rails 6.1.5
となっております。
解決策を教えて頂けないでしょうか。
宜しくお願い致します。
