the script doesn't work when changing the save directory

when you change the directory for saving GIF files, the script does not work in the player, and fonts are not displayed when you press the keys

local options = {
    **dir = "C:\Users\overe\Desktop\screenshot",**
    rez = 600,
    fps = 20,

I change the location in this location and the script doesn't work in the player. 
or am I doing something wrong?
