Can’t unlock APFS external drive


I’ve recently come across an issue with my external HDD (2TB, LaCiE) drive which is formatted with APFS. I have three volumes under a 2TB container which are all APFS (Case-sensitive, Encrypted).

  1. When plugging in the drive, I see the following error for each of my volumes:
    Can’t unlock APFS external drive

  2. When trying to recover with Disk Drill, which has worked in the past, I only see "Updating disk list…"
    Updating disk list...

  3. When usig libfsapfs‘s fsapfsinfo, tool, I see the following error:

fsapfsinfo 20210424

Apple File System (APFS) information:

File system hierarchy:
Unable to print file system hierarchy.
libfsapfs_internal_volume_unlock: invalid volume - missing key bag.
libfsapfs_volume_unlock: unable to unlock volume.
info_handle_get_volume_by_index: unable to unlock volume.
info_handle_file_system_hierarchy_fprint: unable to retrieve volume: 0.

Any and all help would be appreciated! Thanks :~)
