Try this:
- Press Windows Key + R on your keyboard.
- Key in PowerShell and hit Enter.
- Right click on the PowerShell icon on the taskbar and select Run as Administrator.
Now paste the following command in the Administrator: Windows PowerShell window and press Enter key:
Get-AppXPackage -AllUsers | Foreach
Wait for PowerShell to execute and complete the command. Ignore the few errors (in red color) that may pop up.
When it finishes, try hitting Start and hopefully it’ll start working. If not, this solution won’t apply to you, unfortunately.
