I am aware of an issue with the version of the PSF that the MSIX Packaging Tool uses that might be your issue (this is addressed in the TimMangan fork). The issue is in how PsfLauncher locates the powershell.exe to run. On systems that never had the old powershell it fails to find it by registry lookup. I believe it needs
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\PowerShellEngine
to be present on the system. A process monitor trace would show the failed registry request if this is the cause of your issue.
