The error code indicates that the SQL Backup extended stored procedure could not get access to the SQL Backup server components shared object. This can happen if you changed the SQL Server service's startup account.
Could you please try restarting the SQL Backup Agent service and see if it resolves the issue? Once restarted, try running a test backup via Management Studio e.g.
EXEC master..sqlbackup -sql "BACKUP DATABASE model TO [<AUTO>]"'
