My main Microsoft account was hacked, the hacker replaced my email address with theirs, and I can no longer access my account

I have every piece of evidence proving that I am the legitimate owner of this Microsoft account, including ownership of my Minecraft purchase on the account. I have already tried the Account Recovery (ACSR) form multiple times without success and have exhausted all available recovery options. I even reached out publicly on X and tagged Microsoft Support, but I still haven't received any meaningful help.

I cannot afford to lose this account. It contains purchases, data, and years of history. I am willing to provide any proof of ownership required, including purchase records, account details, screenshots, and other verification information. I urgently need assistance from a Microsoft representative to recover access to my account.
