VM e2e caught a reboot loop: Configure-Kiosk used `Invoke-CimMethod -InputObject $wesl` for SetDefaultShell/SetCustomShell, but WESL_UserSetting exposes STATIC methods and Get-CimInstance returns null — so those calls threw "InputObject is null" while the class-level SetEnabled($true) had already succeeded. Result: Shell Launcher enabled with NO shell configured -> every logon (incl. OOBE defaultuser0) gets a broken shell -> the "Why did my PC restart?" OOBE loop. Fix: call SetEnabled/SetDefaultShell/SetCustomShell all class-level (-Namespace/-ClassName). Setting the DEFAULT shell to explorer.exe is what keeps OOBE/normal logons alive; only sm-bootstrap gets the kiosk launcher. Added GetCustomShell verification + a fail-open rollback (SetEnabled false + RunOnce launch of the Welcome app) so a WMI hiccup can never brick the box again. Same class-level fix applied to BootstrapService.RevertKioskAsync. Found via VM 102 disk logs (silvermetal-firstboot.log + silvermetal-kiosk.log).
