MacRumors:

There was a problem with the firmware on the Apple T2 security chip that prevented some users from being able start their Macs after updating to the ‌macOS Monterey‌ software.
Apple says that a BridgeOS firmware update is now included with the existing macOS updates to prevent further failures, and users already impacted by the issue should contact Apple Support for assistance with their machines.
