[Version 3.3.4] Resolved an issue causing some users to crash

I removed the cause of the crash by having the user who was experiencing the crash check it out.

So I reverted the source code to version 3.3.1 and implemented the "Unity animation clip export function" and "preset character changes" again. I have already confirmed that it works correctly with the help of users who actually experience crashes. It was a very hard work weekend. Hope you have a good weekend.
