To fix 'Something went wrong. Try to reopen Settings later', try to re-register Settings app:
- Open administrative Windows PowerShell.
- In PowerShell window, type/paste following cmdlet and press Enter key:
Get-AppXPackage -AllUsers -Name windows.immersivecontrolpanel | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml" -Verbose}
Let the command complete.
