「これはブラウザの問題であり、しばらくすると解決される予定です。Google サーバーの終了または拡張機能の一部が原因であることを願います。

1. Chrome をシークレット モードで使用した場合や、Edge などの他のブラウザで使用した場合にも問題が解決するかどうかを確認できますか?

2. Chrome のすべての拡張機能を削除して、メールを送信してみてください。

Chrome でブラウザのキャッシュと Cookie をクリアしてから、メールを再度送信してみてください。さらに重要な点として、Salesforce の機能に干渉している可能性のある拡張機能を確認すると、原因を特定するのに役立ちます。そのため、提案としては、Gramarly などのブラウザからすべての拡張機能を削除すると、問題が解決します。」

受信者Idに　Emailとメールアドレスが設定されているのが問題だと思います。
ここは!LOOP.Id　ではないでしょうか？

  I actually found that one and could not locate the Global Action to assign it to the proper target.  After a Salesforce ticket, turns out it was something they had to enable on their end.
