catch exception

Hello guys,

Our game has been released and we found a crash reported by users which can not reproduce on our devices. the call stack is following. we added a try catch block to the function, but we are not sure if it can catch the exception since we turned the "fast but on exception" option on. I really appreciate if somebody can give an opinion.

thanks in advance
