Greetings!
This is Tin, I'm happy to help you. Looks like you're experiencing activation issue with your Windows after updating your BIOS. Let me help you with that.
If I may ask, have you tried to run the Windows Activation Troubleshooter already? Since you're using a Digital license, please make sure that the correct MS Account is signed in. Please click Start menu and type Activation then hit enter. Run the Troubleshoot and choose "I've recently replaced my hardware". Please follow the prompt and check if it will resolve your case.
Please let me know how it goes.
Thanks,
Tin
