Welcome to the community! Glad you got it resolved. The current date/time is a known issue with Windows 11 as there are some checks that get done upon installation and if the time is off; the installation does not go through correctly. I thought this might be Bitlocker related; though it could be related to the actual setup of Windows itself when it creates its client side keys for activation.
Modern encryption protocols do not have a lot of tolerance for a system that is out of sync with time. Enjoy your Framework Laptop.
