Code:

var loginHandler = JELoginWrapper.Instance.LoginHandler;
//var session = await loginHandler.AuthenticateInteractively();
var authenticator = loginHandler.CreateAuthenticatorWithNewAccount();
authenticator.AddForceMicrosoftOAuthForJE(oauth => oauth.Interactive());
authenticator.AddXboxAuthForJE(xbox => xbox.Basic());
authenticator.AddForceJEAuthenticator();
var session = await authenticator.ExecuteForLauncherAsync();
Console.WriteLine("Logged in successfully with account " + session.Username + ".");```

Why is this happening? And what's the fix?

Btw I'm using .NET WinForms, is that the issue?

I also tried this:

var loginHandler = JELoginHandlerBuilder.BuildDefault();
//var session = await loginHandler.Authenticate();
var session = await loginHandler.AuthenticateInteractively();
Console.WriteLine("Logged in successfully with account " + session.Username + ".");

But I still get the same issue.

So I found the solution, and the issue.

Issue: WebView2 & Fody.Costura packages

Solution: All you have to do is literally just update the packages that come with CmLib's packages (including WebView2, Fody.Costura). It's been fixed in the new versions so that's great. I recommend you pin this issue just in case anyone has the same one.

I also suffered this issue with WebView2 and Fody before. thank you for reporting
