I'm seeing a reproducible hang in fully command-line-driven builds that started right after the 8/18 update (v2026.08.11704). The same preset and image worked fine via CLI automation before that update, and still completes fine if I drive it manually through the GUI, it only hangs when run via the command line.

Command Used:
NTLite.exe /Path:"D:\Win11_Pro_Image2" /Load /Index:1 /Preset:"D:\Carlton_Win11.xml" /Apply /CreateIso:"D:\Carlton_Win11.iso" /IsoLabel:"Carlton_Win11" /Exit:AfterApply /NewInstance

The image mounts successfully, and the registry hive load completes normally (confirmed via Windows' own System event log — hive access history cleared for install.wim's mounted SOFTWARE/SYSTEM hives). Right after that, NTLite's own log (NTLite.log) freezes on the line SM [m]: clr and never produces another line. I've let it sit for over an hour with no further progress.

Tried both /Save:save and /Save:stop explicitly, identical hang either way.

Environment:
  • NTLite v2026.08.11704 x64
  • Host: Windows 11 Professional 25H2 x64 (10.0.26200.9168)
  • Target image: Windows 11 Pro, install.wim, index 1

Any ideas how to get this working again?

Thanks,
Chris
