[BUG] MSIXMGR fails to convert msixbundle to vhdx format with error HRESULT 0x8000ffff

[JimMoyle]

Project MSIX SDK or Win7Msix

Describe the bug This happens with many packages, but you can reproduce using the windows terminal msix bundle

Failed with HRESULT 0x8000ffff when trying to unpack Microsoft.WindowsTerminal_Win11_1.12.10983.0_8wekyb3d8bbwe.msixbundle

To Reproduce Steps to reproduce the behavior:

Download The Windows Terminal via WinGet

Run the following msix manager command: & 'C:\Program Files\MSIXMGR\msixmgr.exe' -Unpack -packagePath $fileName -destination $destinationPath -applyacls -create -vhdSize 100 -filetype "vhdx" -rootDirectory apps

Expected behavior A vhdx with the correct app inside. The minimum I would expect is an actionable error statement.
