How To Fix FullyQualifiedErrorId : UnauthorizedAccess - A Powershell Error

The Problem

I was trying to run my express script in VSCode on Windows 11 using the Terminal, and I got back the following PowerShell error:

1
cannot be loaded because running scripts is disabled on this system.For more information, see
2

    + CategoryInfo          : SecurityError: (:)[], PSSecurityException
7
      + FullyQualifiedErrorId : UnauthorizedAccess

The link didn’t work for me.

Luckily, there is an easy fix.

The Solution

Go to Settings > System > For developers.

Look for PowerShell, then turn this option on:

Change execution policy. -> On

Now run your script again, it should be working. You might get asked for permission to run it for the first time.
