Simple WiFi Bug? Value cannot be null. (Parameter 'stream') - wpf

Question

This problem prevents connecting to a new network using Simple WiFi (NuGet, GitHub). For whatever reason, a connection point that already has a profile works just fine.
The problem line is accessPoint.Connect(request). When the password is wrong, this works fine. When the password is right, however, an exception gets thrown from System.Private.CoreLib.
After taking a look at other samples on the web, it seems like everything is done correctly. I therefore created a sample application to reproduce the error (WPF, .NET 6.0):
MainWindow.xaml.cs
using SimpleWifi;
using SimpleWifi.Win32;
using System;
using System.Linq;
using System.Windows;
using System.Windows.Media;
namespace SimpleWiFi_Test_Wpf
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
RefreshAndAssignWiFiConnections();
}
private void RefreshAndAssignWiFiConnections()
{
// Refresh WiFi list
// https://stackoverflow.com/a/65024992/4682228
var client = new WlanClient();
foreach (WlanInterface wlanInterface in client.Interfaces)
wlanInterface.Scan();
Wifi wifi = new Wifi();
var accessPoints = wifi.GetAccessPoints()
.OrderByDescending(ap => ap.SignalStrength)
.Where(ap => !string.IsNullOrEmpty(ap.Name))
.Select(ap => ap.Name)
.ToList();
ComboBox_WiFiConnections.ItemsSource = accessPoints;
ComboBox_WiFiConnections.SelectedItem = accessPoints.FirstOrDefault();
}
private void ComboBox_WiFiConnections_DropDownOpened(object sender, EventArgs e)
{
RefreshAndAssignWiFiConnections();
}
private void PasswordBox_WiFiPassword_PasswordChanged(object sender, RoutedEventArgs e)
{
PasswordBox_WiFiPassword.BorderBrush = Brushes.Transparent;
}
private void Button_WiFiLogin_Click(object sender, RoutedEventArgs e)
{
Wifi wifi = new Wifi();
var accessPointName = ComboBox_WiFiConnections.SelectedValue as string;
var accessPoint = wifi.GetAccessPoints().FirstOrDefault(ap => ap.Name == accessPointName);
AuthRequest request = new(accessPoint)
{
Password = PasswordBox_WiFiPassword.Password,
};
try
{
if (request.IsUsernameRequired)
{
// Doesn't reach: username not missing
}
if (request.IsDomainSupported)
{
// Doesn't reach: no domain supported
}
if (accessPoint.Connect(request)) // This call throws the exception
{
// Success!
// ...
}
else
{
// Wrong password
PasswordBox_WiFiPassword.BorderBrush = Brushes.Red;
}
}
catch (Exception ex)
{
// "Value cannot be null. (Parameter 'stream')"
// at System.ThrowHelper.ThrowArgumentNullException(ExceptionArgument argument)
// at System.IO.StreamReader..ctor(Stream stream, Encoding encoding, Boolean detectEncodingFromByteOrderMarks, Int32 bufferSize, Boolean leaveOpen)

}
}
}
}
MainWindow.xaml
<StackPanel>
<ComboBox x:Name="ComboBox_WiFiConnections" DropDownOpened="ComboBox_WiFiConnections_DropDownOpened" Width="200"/>
<PasswordBox x:Name="PasswordBox_WiFiPassword" PasswordChanged="PasswordBox_WiFiPassword_PasswordChanged" Width="200"/>
<Button x:Name="Button_WiFiLogin" Click="Button_WiFiLogin_Click" Content="Login" Width="200"/>
</StackPanel>
Anyone know why this exception might be happening? A missing parameter? A bug in the library?
Note: it may be others are getting a problem with the same symptoms; question 1, question 2.
