Solved: Unity 5 iOS export with IL2CPP fail

Hi everyone, I'm trying to export my game to iOS, and I got the following error:

I tried a lot of ways to fix it such as change optimize option to .Net 2.0, change Architecture, and change stripping level. None of those works. I was using LitJson, and now I deleted that plugin, the only plugin I'm using right now is iTween. Apple store won't let me upload a 32 bit support app.

Is there anyone else run into the same issue before? Or is there anyone who can help me on this one?

Thanks!
