ConnectNetworkAsync fails when not logged in locally or via RDP

[prushik]

I have an application that runs in the background. Typically, it is started through an RDP connection, but eventually we will run as a service.
Everything works fine when we are still logged in, but if we start running and then disconnect from RDP, we get an exception on ConnectNetworkAsync:

System.ComponentModel.Win32Exception: 'MethodName: WlanConnect, ErrorCode: 87, ErrorMessage: The parameter is incorrect.
'

The following code should help to reproduce the issue:

// give time to log out to trigger the issue
Thread.Sleep(10000);

// create profile
ManagedNativeWifi.NativeWifi.SetProfile(iface.Id, ProfileType.PerUser, CreateProfileXml(ssid+"_test", ssid, passwd), null, true);

// the following line works correctly while logged in, but throws an exception when logged out
bool connect_success = ManagedNativeWifi.NativeWifi.ConnectNetworkAsync(iface.Id, ssid + "_test", BssType.Infrastructure, new System.Net.NetworkInformation.PhysicalAddress(Array.ConvertAll(bssid.Split(':'), x => Convert.ToByte(x, 16))), new TimeSpan(0, 1, 0), new CancellationToken()).GetAwaiter().GetResult();

// ... snip ...

private static string CreateProfileXml(string profileName, string ssidString, string password) =>
