Apple has fixed an issue with its T2 security chip that caused boot issues from some users who upgraded to macOS Monterey.

The company provided the following statement to Rene Ritchie confirming the fix...

We have identified and fixed an issue with the firmware on the Apple T2 security chip that prevented a very small number of users from booting up their Mac after updating macOS. The updated firmware is now included with the existing macOS updates. Any users impacted by this issue can contact Apple Support for assistance.

Didn't work for me. I got this error: "A required firmware update could not be installed. Compatible internal storage is required in order to update."
