Game stops when button is clicked to serialize data and change scene, but no error log from Unity

Question

As you can see in the title, When I run my game in the Unity editor, I click a button after entering a username into an input field that serializes the name and loads the next scene. The problem is that when I click the button, the game freezes and Unity stop responding, but when I remove the code that serializes the name, it loads the next level no problem. I have attached the code that gets the name from the input field, the code that serializes the name and the code that loads the next scene in that order. The problem is most likely in the serializing code, but I'm not entirely sure what the problem is. I edited the code and replaced the code below as Yuri Galiza requested. To see the problem first hand and to get some better context as to what the code is doing, please use this link: https://drive.google.com/drive/folders/0BynpT6Viy1xdR0IwWmV6T3RRU2s?usp=sharing

Well, probably the application is dying before the Log is called. Try placing logs at different places throughout the code. And then you'll probably find the place with the problem.
