StackOverflow On PlayFabClientAPI.ForgetAllCredentials();

Currently, I try to Logout my user with the PlayFabClientAPI.ForgetAllCredentials() call. But I receive a StackOverflow every time I try to do so. Do I miss something?

public static void LogIn(string _email, string _password)
        {
            if (m_LoggedIn) { return; }


            LoginWithEmailAddressRequest loginRequest = new LoginWithEmailAddressRequest { Email = _email, Password = _password };
            PlayFabClientAPI.LoginWithEmailAddress(loginRequest, loginResult =>
            {
                GetPlayerProfileRequest getPlayerProfileRequest = new GetPlayerProfileRequest { PlayFabId = loginResult.PlayFabId };
                PlayFabClientAPI.GetPlayerProfile(getPlayerProfileRequest, profileResult =>
                {
		    // Removed some private code but nothing related to playfab
                    m_LoggedIn = true;
                }, error =>
                {
                Debug.Log(error.ErrorMessage);
                });
            },
             error =>
             {
             Debug.Log(error.ErrorMessage);
             });
        }

public static void LogOut()
        {
            PlayFabClientAPI.ForgetAllCredentials();
            m_LoggedIn = false;
        }
