Managing personal Outlook.com account settings, security, and privacy
I understand your frustration.
Unfortunately, purchased or redeemed licenses, such as your Minecraft game, are permanently linked to the account on which they were acquired.
In this case, you may need to consider purchasing Minecraft again using a new Microsoft account.
If your payment method is still linked to your hacked account, you will need to contact your bank immediately and request to freeze all charges from Microsoft to prevent unauthorized purchases.
You may also need to request a new payment method.
Lastly, you may reach out to Microsoft Support as they can possibly "Suspend" the account permanently once they have confirmed that the account can no longer be recovered in order to prevent the hacker from using it:
Type "Microsoft 365 sign-in problem" > Click "Get Help" > Scroll down and select the option "Sign in to contact Support" > Microsoft 365 and Office > Billing and Account Profile Questions > Confirm > then select "Chat with a support agent in your web browser"
