You have a number of options:
- Try again, delete the entire ContentDeliveryManager folder / restart your machine > reinstall the folder: (run using Powershell as Admin) Get-AppxPackage Microsoft.Windows.ContentDeliveryManager -allusers | foreach {Add-AppxPackage -register "$($_.InstallLocation)\appxmanifest.xml" -DisableDevelopmentMode} Of course Edge and Settings are set to ON in Privacy Settings. Click Win Key + L to check if Spotlight is working.
- If possible, compare the setup on a comparable machine that runs Spotlight "...normally."
- Last Restore: Upgrade win 10 pro without losing programs or files. Sometimes this works like for restoring the ability to change the Account Picture.
That's all the suggestions I have....
