How to clear secret_key and reset MIAB

Hi all, I am in a weird state with MIAB. I have backups to S3 working and have even done a local backup manually but when trying to restore any of the backups they fail with the following error:

root@box:/home# sudo -E duplicity restore --force file:///home/backup /home/user-data/
Synchronizing remote metadata to local cache...
Copying duplicity-full-signatures.20210721T000411Z.sigtar.gpg to local cache.
GPGError: GPG Failed, see log below:
===== Begin GnuPG log =====
gpg: AES256 encrypted data
gpg: encrypted with 1 passphrase
gpg: decryption failed: Bad session key
===== End GnuPG log =====

While ideally Id like to just get the backups to be restore-able, It seems like my best option would be to simply try to clear all my backups and generate a new secret key and then attempt to create a new backup. I am open to trying other options though.

Prior to running this, did you run:

export PASSPHRASE=$(cat your_backup_secret_key_file.txt)

As per:

Yes I did, and I even confirmed the value was correct by running echo $PASSPHRASE to dump the value

What version of MiaB is this from?

It should be the latest, 0.54
