Hello Rosa,
Thank you for reaching out to Microsoft Support forum.
I can understand you're locked out of your MSI laptop because a BIOS update triggered BitLocker to request a recovery key, which you can't access due to using a local account instead of a Microsoft account.
Windows requires a BitLocker recovery key when it detects a possible unauthorized attempt to access the data. This can also happen if you make changes to the hardware, firmware, or software, which BitLocker cannot distinguish from a possible attack. In these cases, BitLocker might require the extra security of the recovery key even if the user is an authorized owner of the device.

What You Can additionally try:
- Look into Your Microsoft Account:
Even if you think you used a local account, it’s worth checking if BitLocker saved the key to a Microsoft account you might’ve used at some point:
1**.** Look for a Saved Key:
When BitLocker is first enabled, Windows may prompt you to save the recovery key:
Check your email inbox for any message from Microsoft with the key
Look through your files for a
.txtfile labeled “BitLocker Recovery Key”
Check any USB drives you might’ve used recently
I hope the information helps!
