はじめに
ある日、いつも通りTerminalからAmazon Qを呼び出し、チャットしていたら…
「Terminalが突然クラッシュして起動できない！」
という事態に遭遇しました。
再起動してもダメ、なにかのバグか？と思いきや、意外とシンプルな原因＆対処法で解決できたので、備忘録としてQiitaに残しておきます。
同じ症状で困っている人の助けになれば幸いです！

原因：Terminalの「復元情報」が壊れていた
Terminalには、前回開いていたウィンドウの状態を記憶して「自動復元」する機能があります。
しかしこの復元データが破損してしまうと、起動時にクラッシュすることがあります。
自動復元機能はOFFにすることもできますが、私の場合はONにしていました。
対処法：ウィンドウ復元情報のリセット
以下の手順で、Terminal の復元データを削除することで解決しました。
手順
- Finder を開く
- メニューバーから「移動」>「フォルダへ移動...」を選択
- 以下のパスを入力して Enter：
~/Library/Saved Application State/com.apple.Terminal.savedState - 開いたフォルダ内のファイルをすべて削除
※ このとき Terminal は終了しておくこと！ - Terminal を再起動
結果
無事にTerminalが起動するようになりました！
復元情報が原因とは気付きにくいですが、Macでは意外とよくあるようです。
