Unity集成Firebase邮箱/密码认证时出现内部错误的排查求助

我一直在尝试给我的Unity项目集成Firebase认证功能，但每次登录我在Firebase控制台创建的测试账号时，都会遇到同一个错误：

An internal error has occurred

按钮点击时触发的函数如下：

public async void LoginButton()
{
    await SignIn(emailField.text, passwordField.text);
}

而SignIn函数的实现是这样的：

public async Task<bool> SignIn(string email, string password)
{
    try
    {
        var result = await auth.SignInWithEmailAndPasswordAsync(email, password);
        user = result.User;
        Debug.Log($"User signed in successfully: {user.Email}");
        return true;
    }
    catch (FirebaseException e)
    {
        Debug.LogError($"Failed to sign in: {e.Message}");
        return false;
    }
}

Firebase的配置我应该是做对了——Google-services文件已经放在了Unity项目的Assets/Firebase路径下。

我还做了个测试：如果留空输入框，会收到不同的错误提示。比如邮箱为空时，会显示“邮箱格式不正确”，这说明函数本身应该没问题，问题可能出在Firebase端，但我完全不知道该怎么排查Firebase里的问题。目前邮箱/密码认证方式已经启用，控制台里的各项配置看起来都正常。

Edit:

这里是完整的调用栈：
