Unable to execute a powershell script from c#

Question

I've done the following code to execute a powershell script:

public static void LaunchCommand(string command, IList<String> arguments)
{
    Console.WriteLine($"Launching powershell command: {command} {String.Join(" ", arguments)}");
    using (PowerShell ps = PowerShell.Create())
    {
        // specify the script code to run.
        ps.AddScript(command);
        ps.Streams.Debug.DataAdded += OnDebugAdded;
        ps.Streams.Information.DataAdded += OnInfoAdded;
        ps.Streams.Warning.DataAdded += OnWarningAdded;
        ps.Streams.Error.DataAdded += OnErrorAdded;
        //Transformation into a non-generic version
        ArrayList argumentsList = new ArrayList();
        foreach (string argument in arguments)
        {
            argumentsList.Add(argument);
        }

        // specify the parameters to pass into the script.
        ps.AddParameters(argumentsList);

            Collection<PSObject> pipelineObjects = ps.Invoke();

        // print the resulting pipeline objects to the console.
        foreach (var item in pipelineObjects)
        {
            Console.WriteLine(item.BaseObject.ToString());
        }
        Console.WriteLine(ps.HadErrors+" -"+ps.HistoryString);
    }
    Console.WriteLine("Commaned finished");
}

(the .DataAdded just write to console.writeline the new message)

But I hit this:

Launching powershell command: F:\Dev\AAA\scripts/start.ps1 F:\Dev\AAA\scenarios/BBB/config.json

I've searched a lot, I've executed as admin this commands, both in x86 and x64 commands prompt:

Set-ExecutionPolicy -ExecutionPolicy Unrestricted

And if I execute this myself(copy paste in the command line) it works, it only fails when launching from visual studio.

Any idea what is going on?

I'm on windows 10 pro(latest updates) + VS2019(latest updates also). The console app that I'm doing is on .Net Core 3.1. I do run VS as my simple-normal user(as will the end program).

What about sending the command to set the execution policy. Check this. — user1672994

@user1672994 oh? It works! Seems weird security, that an user cannot execute script but can execute the commande to allow it? Anyway, could you add this as answer? — J4N

You can set the execution policy as command in power-shell object.

 powershell.AddCommand("Set-ExecutionPolicy").AddArgument("Unrestricted")
    .AddParameter("Scope","CurrentUser");

Well, apparently in the other system we have, this isn't enough at least :(
