Receive `Specified method is not supported.` for multiple module cmdlets under SYSTEM context.

Brief description of your issue

It's been exciting to see 1.6.3133.0 of the PowerShell module, its really starting to come together.

While the main cmdlets like Get-WinGetPackage, Install-WinGetPackage and Uninstall-WinGetPackage are working well, other ones that I require such as Get-WinGetVersion and Repair-WinGetPackageManager are not, and they're crucial as during a Windows Autopilot sequence, I need to ensure an appropriate version of WinGet is available vs. whatever the system ships with.

Steps to reproduce

1. Open PowerShell 7.x as SYSTEM
2. Call Get-WinGetVersion and observe error occurs.

Expected behavior

C:\Windows\System32>pwsh.exe -ExecutionPolicy Bypass -MTA
PowerShell 7.4.0
PS C:\Windows\System32> whoami
nt authority\system
PS C:\Windows\System32> Get-WinGetVersion
v1.6.3133
PS C:\Windows\System32>

Actual behavior

C:\Windows\System32>pwsh.exe -ExecutionPolicy Bypass -MTA
PowerShell 7.4.0
PS C:\Windows\System32> whoami
nt authority\system
PS C:\Windows\System32> Get-WinGetVersion
Get-WinGetVersion: Specified method is not supported.
PS C:\Windows\System32>

No source files or tests are named. Reproduce the failure under a SYSTEM PowerShell 7.x session, then trace the module entry points for Get-WinGetVersion and Repair-WinGetPackageManager; done means these cmdlets work in that context and Get-WinGetVersion returns the installed WinGet version instead of the unsupported-method error.
