I'm trying to launch Roblox from C#, but it seems it cannot find the Roblox-protocol.

I tried the code I use in Windows run and it did find it, but once I tried it with Process. Start it says the file could not be found.

public static string LaunchRoblox(string authTicket)
{
    Random rnd = new Random();
    long browserTrackerId = 55393295400 + rnd.Next(1, 100);
    TimeSpan t = (DateTime.UtcNow - new DateTime(1970, 1, 1));
    int launchTime = (int)t.TotalSeconds * 1000;

    string url = $@"roblox-player:1+launchmode:play+gameinfo:{authTicket}+launchtime:{launchTime}+placelauncherurl:https://assetgame.roblox.com/game/PlaceLauncher.ashx?request=RequestGame&browserTrackerId=" + browserTrackerId + "&placeId=185655149&isPlayTogetherGame=false+browsertrackerid:" + browserTrackerId + "+robloxLocale:en_us+gameLocale:en_us";

    return url;
}

static void Main(string[] args)
{
    Program.x_crsf_token = GetXCSRFToken();
    Console.Write("Sucessfully obtained X-CRSF-Token: " + Program.x_crsf_token);
    Console.WriteLine("");

    string AuthTicket = GetAuthTicket();
    Console.Write("Sucessfully obtained AuthTicket: " + AuthTicket);
    Console.WriteLine("");

    string joiner = LaunchRoblox(AuthTicket);
    Console.Write("Trying to launch roblox with:" + joiner);
    Console.WriteLine("");
    
    var game = Process.Start(joiner);
    game.WaitForExit();
}
