Error-Duplicati.Library.Main.Controller-FailedOperation

[Gotit]

Hi - I updated Duplicati tot the latest version 2.2.0.3 yesterday and now my backups fail with the following:

"2026-01-23 15:38:43 -05 - [Error-Duplicati.Library.Main.Controller-FailedOperation]: The operation Backup has failed with error: Could not load type 'Duplicati.Library.Snapshots.UsnJournalService' from assembly 'Duplicati.Library.Snapshots, Version=2.2.0.3, Culture=neutral, PublicKeyToken=null'.\nTypeLoadException: Could not load type 'Duplicati.Library.Snapshots.UsnJournalService' from assembly 'Duplicati.Library.Snapshots, Version=2.2.0.3, Culture=neutral, PublicKeyToken=null'."

This is on an Endeavour/Arch install. Could you please point me toward what I need to do to resolve this issue?
Thanks
