I have a double whammy of an issue here, I know I can use...

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

If in admin PowerShell to fix the start menu but when I try I get a The database disk image is malformed Error in PowerShell.
I was told these steps to fix it...

a. Navigate to %AppData%\..\Local\Microsoft\Windows or
b. copy that in Run and execute to open File Explorer.
2. Rename Usrclass.dat to something like Usrclass.dat.old
3. Press Ctrl+Alt+Delete and sign out.
4. Sign in again and done.

However, Usrclass.dat is constantly in use by the System and cannot be renamed and I can't make another User Account for some reason.
