Although the causes of the error are not specified, there are possible solutions that can be tried before resorting to wiping the drive and reinstalling MacOS. If all other options have been exhausted and there is no important data on the drive, or it has been successfully recovered, wiping and reinstalling MacOS in recovery mode may be the most effective solution. Remember to always back up your data before attempting any troubleshooting steps.
