what can i do when i didn't add my phone number to my hacked account with changed email?

You may have used this email as a back up or it is attached to the account. Did you change the email on the account before? Or try logging in with your phone number if it takes you to another account.

I have a phone number on the account, and that number is not associated with any other account. I only have 1 email attached to my account.

My Microsoft account got hacked. The hacker was baiting me to get him verification codes of changing the security info of my account, then got raid of my account.

He deleted the original email of my account which is "*** Email address is removed for privacy ***" then somehow changed the account email to another one named
"*** Email address is removed for privacy ***" (These info is shown in first image, check attachments).
After doing so, he got raid of all my security stuff like verify phone number and email.He was clearly hacking my account. He literally deleted my original email of this account "*** Email address is removed for privacy ***", if he is not hacking this account, he has no need to do it...

I really need help!

"My Microsoft account got hacked. The hacker was baiting me to get him verification codes of changing the security info of my account, then got raid of my account."

You didnt actually give him the verification codes did you? If so this would've been what allowed everything else that happened afterwards to occur.

and also hacker manage to remove my phone number from the account also.
