Windows 10 SearchUI.exe failure

[TomL_13655]

Cortana does nothing when I say, "Hey Cortana" I tried opening it manually and it opens and closes before displaying any text. This happens with all the users on the PC.

SFC and DISM show no errors.

Event Viewer shows this:

I tried reinstalling Cortana in PowerShell with this:

Get-AppxPackage -AllUsers Microsoft.Windows.Cortana | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}

but no change.
