Deployment of WindowsAppKiosk to Self-Deployed enrolled devices

Hi,

I have been trying to deploy this package for a few weeks now with no luck. I keep running into issues with the win32 app installation failure.

We have teste don both User affinity enrolled devices and self-deployed enrolled devices. Both are sitting on "Waiting for install status".

I am testing on both Windows IoT 2024 LTSC Eval and Windows 11 Enterprise devices. Both show the same issue.

We have run through everything we can think of:

- Checked IME and confirmed setup and working
- ESP configuration complete, neither OOBE or ESP tasks pending
- Signed ps1 scripts in package incase MOTW was blocking PowerShell scripts
- Enabled Shell Launcher feature on the device

This is the problem we can see on the UA device: "Shell Launcher configuration failed. Computer should be restarted first."

We have restarted this multiple times and still get the issue, even the remediation script to check if Shell Launcher feature is enabled forces a restart once it runs.

The Self-Deployed device is just sitting on the Windows login screen, it has completed OOBE and ESP but is also not deploying when added to the group the Kiosk App is assigned to. This is a device group, the App is set to run in SYSTEM context.

Even when we try to manually run the install command in PowerShell on the User Affinity device we get the following issue when running powershell.exe as a domain admin:

Any ideas on how to fix this or what could be the cause? Are there any pre-requisites required that are not listed in the GitHub repository?

Thanks,
