PSGallery module gone - add it back to PowerShell-ISE

Unable to add modules from the PSGallery provider

When your Package provider list is empty:

Get-PackageProvider -ListAvailable

Run CMD.exe as an administrator and run the following command:

@powershell -NoProfile -ExecutionPolicy Bypass -Command "iex 

((new-object net.webclient).DownloadString('https://chocolatey.org/

install.ps1'))" && SET PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin

Close the CMD window, now you have a PS Repository:

PS C:\windows\system32> Get-PSRepository            
            
Name                      InstallationPolicy   SourceLocation

---------                 ------------------   --------------   

PSGallery                 Untrusted              https://www.powershellgallery.com/api/v2/

Set the PSGallery as trusted:

PS C:\windows\system32> Set-PackageSource -Name PSGallery -Trusted               
            
Name                             ProviderName     IsTrusted  Location            
---------                        -------------    ---------  --------
