Having an exe run in bg, unity still responsive

I have an exe that is started by unity, that when it starts sends input to unity that i can use.

I have a problem, that when those exe's start up , it "freases" unity and you are not able to continue playing your game.

How do i send those console windows to the background and stop it affecting unity at all?

Images attached to what i mean, and my code snipped added below (the minimize part in my code didnt work by the way.. dont know if im doing it wrong..)

 Process p;
     // Use this for initialization
     void Start () {
         
         ProcessStartInfo info = new ProcessStartInfo();
         
         //Process.Start(@"Directory");
         
         info.FileName = @"Directory";
         info.WorkingDirectory = @"Directoryalt text";
         info.Arguments = "";
         info.UseShellExecute = false;
         info.RedirectStandardOutput = true;
         //info.WindowStyle = ProcessWindowStyle.Minimized;
         info.WindowStyle = ProcessWindowStyle.Hidden;
         
         p = Process.Start(info);
         
         if ( p != null )
         print(p.StandardOutput.ReadToEnd());
     }
