Start menu not working

I found the following article, ran the suggested powershell command and my start menu is working again. Here it is as I found it:
Go to Start menu button and right click on it. This will open the contextual menu, after which you need to select Command Prompt (Admin). Once Command Prompt is open, go ahead with the following steps.

• Type and enter: Powershell
• Type the following: Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}

I followed the direction (I suggest you to follow the steps provided below and check if it helps.

• Type Powershell
• Type the following 2 commands in the Powershell prompt:
  
  $manifest = (Get-AppxPackage Microsoft.WindowsStore).InstallLocation + '\AppxManifest.xml' ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest

Get-AppXPackage -AllUsers |Where-Object {$_.InstallLocation -like "*SystemApps*"}

• Close the Powershell window.
• Reboot,)

How to change the WinX menu, including Powershell/Powershell (Admin)

This part intrigues me. As suggested earler, please post a screenshot of the error message. Also, please clarify/test the follwoing:

1. Can you start PowerShell from the Start Menu?
2. If you navigate to %localappdata%\Microsoft\Windows\WinX\Group3, does PowerShell launch from the shortcuts there?
3. If #1 works & #2 doesn't, compare (& post) the target text from each shortcuts properties. For the Start Menu shortcut, right-click & select Open file location to navigate to the Start Menu folder.
