Windows 10: Can't activate Windows 11 after BIOS update

In my PC I have an Asus motherboard and recently applied a BIOS update, which included an update to the TPM chip.My Windows 11 Pro is no longer activated, and I've tried as many things as possible to get it working without any luck.I'm an IT professional certified in Azure and various other Microsoft products, but I am all out of ideas with this one, so I logged a case with Microsoft on 11/11/23 but according to the status, an agent hasn't even been assigned.How can I activate Windows again? None of my physical hardware has changed.

Cant Activate Windows 11 after BIOS Update !

Updating your motherboard's BIOS should not affect your Windows 11 activation, as activation is tied to your Microsoft account, not your hardware. However, it's possible that something went wrong during the BIOS update that caused your Windows 11 activation to be lost.

To resolve the issue, you can try the following:

1. Check that you're signed in to Windows 11 with the same Microsoft account you used to activate it.
   
2. Go to Settings > Update & Security > Activation and click on "Troubleshoot" to run the activation troubleshooter. Follow the on-screen instructions and select "I recently changed hardware on this device" when prompted.
   
3. If the troubleshooter doesn't work, try using the "Change product key" option in the Activation settings to manually enter your product key. You can find your product key on the Windows 11 packaging or in the email from Microsoft when you purchased the license.
