F3 0F 11 47 10 49

this is the base array of byte(i cant upload png)
E9 73 51 CB FF 49
and this is the when script executed it works perfect
but when i dont click activate script and try to change value manually to E9 73 51 CB FF 49 my game closes can someone say why

edit:it works when i activate script and change value to normal (F3 0F 11 47 10 49) it works as if i didn't activate the script but the opposite doesn't work.
