The culprit behind this issue is Advanced Data Protection [ADP]. To be more specific, you are facing this error because you did not turn off ADP before downgrading the OS. Since the ADP encryption keys are stored on the device, so when you went into DFU mode, the encryption keys were deleted from the Secure Enclave and were most probably not backed up either.

Moreover, Apple has already mentioned on its ADP page that “If you use Advanced Data Protection, you’re responsible for your data recovery. Because Apple won’t have the keys required to recover your data, you’ll need to have a Recovery Contact or Recovery Key set up on your account”. So their support team might not be of much help either. With that said, what about if the user has their Recovery Key set up? Unfortunately, even that might not work.
