Kioskmode with Powershell - Can't start App 0xffffffff

Question

I would like to set Edge as an Assigned Access to a User. I'm using the following PowerShell Command:

Net localgroup administrators /add

Net localgroup administratoren administrators /add

$user = "KioskUser"
$userDesc = "Kiosk account with assigned Access"
New-LocalUser -Name $user -NoPassword -AccountNeverExpires -UserMayNotChangePassword -Description $userDesc | Set-LocalUser -PasswordNeverExpires $true
Add-LocalGroupMember -Group "Benutzer" -Member "$user"

Set-AssignedAccess -AppUserModelId Microsoft.MicrosoftEdge_8wekyb3d8bbwe!MicrosoftEdge -UserName $user

The Skript works, but if i want to log in as KioskUser i always get the following error (translated from German):

"Your app could not be launched. Press CTRL+ALT+DELETE to log out or contact your system administrator. Search online for the error code 0xffffffff to get more Information."

Does anyone know how to solve this?

Im Using PS version 5.1.19041.1682

Your system may not allow accounts with no password and never expire. — jdweng

Microsoft.MicrosoftEdge_8wekyb3d8bbwe!MicrosoftEdge is AppUserModelId for Legacy Edge. The AppUserModelId for Edge Chromium is MSEdge.

So the PowerShell script sets Legacy Edge to kiosk mode but now we use Edge Chromium, that's why you can't login.

It's true that we can't use PowerShell to set up kiosk mode for Edge Chromium as it's not a UWP app. For configuring Edge Chromium kiosk mode, you can refer to this doc. After following the steps in the doc, then you can login Edge kiosk mode successfully.

Yess, thank you very much. But this doc only shows it with a GUI and i need to do it with Powershell. But it seems like its harder than i expected because of the Edge Chromium

@spoon2 Seems we can't use PowerShell to set up Edge kiosk mode as PowerShell method only works for UWP apps.
