W10 LTSC 1809 Software Updates Task Sequence Issue

[DavidBrookes]

In my Windows 10 LTSC 1809 task sequence, the Install Software Updates step is failing to run. I have attached the log files for the latest attempt to build a test machine. I have deployed the required software update group to both the Unknown Computer collection (as I am deleting the SCCM object for the test machine before each test build) and to a common collection that all of the test machines are put into. The machine does receive and install updates post-build successfully so it is not the software update group or the deployment package as far as I can tell.
