Start by reproducing Get-WinGetPackage from the WinGet CLI and PowerShell Module in SYSTEM context, using the reported v1.12.440 environment, then compare it with a user-context run. Done means the command no longer exits with code 1 and returns or exports the installed package list as it did before the December update.
