After updating bios I cannot reactivate windows 11

Hello,

I recently updated my Bios for the first time I found I had the error 0xC004F211. I tried everything and for some reason no matter the method attempting to use my key does not work. I bought the key from the Microsoft store back in early 2023 and my account is a offline account and the troubleshooter was of no help either. When I tried entering my existing key it told me the key either does not work any longer or is not real which cannot be the case. I even tried signing in on my account that bought the key as admin and that still did not clear up the issue.

I can provide any information even a purchase number to prove I own the key. I do not have the ability nor should I have to buy another license.

Any help would greatly be appreciated.
