Troubleshooting after using Windows Utility

I’m running windows 10 up to date since its end of life. I ran the WinUtil from the Titus site. Specifically the Tweaks, now I’m unable to rerun the WinUtil script. This is the error I get in powershell:

irm : The request was aborted: Could not create SSL/TLS secure channel.
At line:1 char:1

  • irm christitus.com/win | iex
  •   + CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebExc
     eption
      + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand
    

powershell is running with administrator privileges. Could I get some assistance with this? I don’t usually run scripts like this, so this is new for me. Thanks
