I cannot reproduce the problem you describe.
I created a simple implementation using your code and I can change the master volume without any issues.

static void Main(string[] args) {
    MMDeviceEnumerator enumerator = new();
    MMNotificationClient notificationClient = new(enumerator);

    while(true) {
        var c = Console.ReadKey(true);
        if(c.Key == ConsoleKey.Escape) break;
        System.Threading.Thread.Sleep(1000);
    }
}

Since you mentioned that your app crashes without any errors, could it be that the app is simply exiting?
