目的：新しいプロジェクト(id: crack-celerity-429215-a2)で作成したapp engineアプリケーションに、awsのroute53から取得したカスタムドメイン” ngrjaku.com”を追加したい。
起きている問題：一度削除保留中にしたプロジェクト（id: quizapp-427407）に当該ドメインがマッピングされてしまっていることで、新しいプロジェクト（id:crack-celerity-429215-a2）のapp engineアプリにカスタムドメインを追加できません。コマンドラインから操作してプロジェクトをquizapp-427407に切り替え、ドメインマッピングを削除しようとしたんですが、「プロジェクトがすでに削除されている」という理由で削除操作ができない状態です。要するに、過去のプロジェクトに一度マッピングし、それを削除保留にしたことで、新しいプロジェクトへのドメインマッピングができなくなっています。
原因はおそらくquizapp-427407プロジェクトを一度削除保留中にしてしまったことでアクセスできない状態になってしまっているからではないかと考えていますがあくまで予想で実際にはなぜ削除できないのか分かりません。
今実現したいこと：過去に作成しもう使わないプロジェクトquizapp-427407に追加したドメインマッピングを削除し、まっさらな状態でもう一度、新しいプロジェクトcrack-celerity-429215-a2内のapp engineアプリにカスタムドメインngrjaku.comを追加したいです。今後しばらくはこの新しいプロジェクト以外使う予定がありません。どうすれば解決できるでしょうか？また、参考になる公式ドキュメントなどがあれば教えていただきたいです。よろしくお願いします。

Title: I want to resolve an error preventing me from adding a custom domain to a new project
Objective: I want to add a custom domain “” (obtained from AWS Route 53) to an App Engine application created in a new project (id: crack-celerity-429215-a2).
Current Issue: I can’t add the custom domain to the App Engine app in the new project (id: crack-celerity-429215-a2) because the domain is still mapped to a project that was previously set for deletion (id: quizapp-427407). When I tried to switch to the quizapp-427407 project via command line to remove the domain mapping, I couldn’t perform the deletion operation because “the project has already been deleted”. In essence, because I once mapped the domain to a previous project and then set that project for deletion, I’m now unable to map the domain to a new project.
I suspect this is because the quizapp-427407 project became inaccessible after being marked for deletion, but I’m not certain why I can’t delete it.
What I Want to Achieve: I want to remove the domain mapping from the old project (quizapp-427407) that I no longer use, and then add the custom domain “ngrjaku.com” to the App Engine app in my new project (crack-celerity-429215-a2) with a clean slate. I don’t plan to use any other projects except this new one for the foreseeable future. How can I resolve this issue? Also, if there are any relevant official documents that could help, I would appreciate if you could share them. Thank you in advance for your assistance.
