Another funny thing is that sometimes the reason that caused the crash is the componnets of MUGEN or the stages, which obviously not the real reason. But the funny thing is that sometimes they worked but sometimes they didn't. I tried to figure it out by testing each character and yes, I saw it crashed. At first I thought the problem is about the new characters that I added to the game, making it crashed continuously. My 1.1 MUGEN keep crashing constantly after I adding some new Blazblue and Under Night-In Birth characters.
