Hey there! Nice to meet you!
I'm sorry you are experiencing this.
The only way to recover a hacked Microsoft/Minecraft account is through the official Microsoft troubleshooter guide:
Since the account is currently blocked, kindly perform these steps to resolve this error:
- Request an account recovery using an InPrivate window or Incognito. Also, try using different devices and network services. https://account.live.com/acsr
- If it doesn't work, wait 24 hours to request an account recovery, but please make sure not to attempt to sign in or reset the password within that timeframe, as this may reset the lock cooldown.
- If the issue persists, try waiting exactly 48 hours before requesting another account recovery.
If the account recovery web form doesn't work, and since the security info has been replaced by the hacker, I'm afraid there is no other working method to recover the Microsoft account, and Microsoft Support cannot help either.
However, I would recommend reaching out to Minecraft Support regarding your Minecraft account if they can provide an alternative option:

Thank you for your understanding.
Best regards,
