Can you create a new local admin account and try those commands to reinstall Settings?

After searching I tried before with:

but without success.

This is winVer results:

When i right click on empty area of desktop and select "Personalize" this is result:

So, the in-place upgrade worked. The only issue you're now facing is with Settings.

Please open admin PowerShell and run:

Get-AppxPackage windows.immersivecontrolpanel | Reset-AppxPackage 

Get-AppXPackage windows.immersivecontrolpanel -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml" -Verbose} 

This resets and reinstalls Settings.

Run "winver.exe" and post a screenshot.
