Bladed Batch terminates with a handled exception stating that the "Sequence contains no matching element".
This is also captured in the Batch log file (C:\Users\XXXX\AppData\Local\Temp\5\GH.BatchFramework.Clinet.log). This results from the corruption of a Batch configuration resulting from a failure to save a job status correctly or a crash during a prior operation.

2021-07-06 12:23:39,462 [14] ERROR GH.BatchFramework.Client.Program - Terminating: True
The simplest resolution to this is the deletion of the contents of the Batch folder: C:\Users\XXXXX\DNV GL\Batch\DefaultBatchDirectory.
WARNING! Deletion of the contents will remove the corrupted element but also the batch configuration - it will need to be re-setup.
