Hello,

Try to re-register Settings app first:

1. Open administrative Windows PowerShell.

2. 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}

3. Let the command complete.

Then try to re-register Start Menu:

Method 1.
Without reset feature, we can't install windows 10 again, but it deletes all installed apps and folders by you.

Method 2
Enable built in Administrator account and then create new account with admin right.
Login into new account, take ownership of files and folders of your corrupted account, copy the personal files to backup location.
Then delete your account and delete your files. Disable builtin Admin account.
