JJSploit not working?

SInce the first of October, I have tried multiple times to open the hacks but i have been unsuccesful. The exploits will not start, specifically the EXECUTOR. Whenever I try pressing it, it closes and reopens my game a lot and causes a lot of lag ,I can only use basic cheats which i dont prefer to.
Can someone tell me how to fix the problem. Thanks!
The game I hack is roblox.
