Hello, thank you for reaching out to Microsoft Q&A.
Did you check your Junk or Spam email folders to see if the verification email from Microsoft ended up there?
If not, try using a different browser or a different Wi‑Fi network and send the verification code again. If you're still unable to receive the code, it's possible that your account is temporarily blocked. I recommend submitting the account reinstatement form directly to the Microsoft account Digital Safety team so they can help reinstate your account if possible.
When you fill out the form, make sure you select "I am not receiving the provided code" as the issue.

Please note that if you're unable to find the BitLocker recovery key, you will not be able to unlock the drive. In that case, you'll need to create a bootable USB installation media and use it to reinstall Windows. This process will completely erase all data on your hard drive (HDD).
