Tested it now and no issues.
However, note that I didn't have your scripts, REGs and updates, so try the following:
- start from a fresh ISO
- use only updates from NTLite's update list
- try once without your REG files, and once without CMD files, to isolate where the issue is
- and depending on the level of UEFI SecureBoot patching of the host machine, try with and without Update boot managers option in the toolbar when integrating updates
