The mailbox cannot receive the message

I am a I am already GPTS Builder. I have a very special problem. It needs to be addressed.
Background: My account is an Apple account. A hidden email that your Apple account automatically starts when you log in to GPT. This is when my OPENAI account shows a hidden email.
However, I deleted my hidden email when I was setting it up. And I can’t get my Apple email account back. But my OPENAI account is still a hidden email.
This is the mailbox that is currently published. I can’t get any email messages.

My question is: how can I change my email? Or restore my normal Apple email account. Let me set GPTS to a normal mailbox that can receive information
