How come JJ doesn't fully work?

For example, I join a game, attach JJ, and it connects, then I click on an exploit, (it works), I want to use another exploit, so I click another option, (game crashes). Why does it do that? Some times, I can click up to 3 differnent exploits, and sometimes, when I click just 1 my roblox crashes? I have had JJ before, many months ago, back in 2025, and I never had this issue with it. I would just like to know how to fix that problem. Other than that, I think JJ is an awesome place for exploits!
