こんにちは、MLBお兄さんこと松村です。
MLB は開幕して1ヶ月が経過しました。その間、我がニューヨーク・ヤンキースは11連勝を記録するなど、AL東地区首位を走っています。（2022/05/14 現在）
私の Azure サブスクリプションに作成している Azure Cloud Shell において az webpp コマンドが動作しなくなりました。
Azure CLI の GitHub リポジトリにフィードバックを行い、解決方法を聞いたので共有します。
エラー内容

CLI 拡張機能を再インストールして解決
回答によると、原因は不明だけど appservice-kube 拡張機能の問題で似たような事象が起きたことがあるとのこと。
appservice-kube 拡張機能を再インストールしてみるとエラーが解消しました。
$ az extension remove -n appservice-kube $ az extension add -n appservice-kube The installed extension 'appservice-kube' is in preview.
$ az webapp
the following arguments are required: _subcommand
Examples from AI knowledge base:
az webapp list --query "[].{hostName: defaultHostName, state: state}"
List default host name and state for all web apps.

※はじめは勘違いして Azure CLI 自体の更新 az upgrade を行おうとしました（コケました）
同様の事象が起きた方は参考にしてみてください。
