how to use this new version of jjsploit 8.15.0

so like i have used jjsploit for a lot of years already but now this new update i want to make a complaint about. so its like when i run there are two buttons legacy and beta. when i click legacy 2 things happen. 1. Jjsploit shuts down. 2. It freezes both roblox and jjsploit. when i click on beta, something pops up and then my game is ok for 5 seconds then it freezes then roblox shuts down. Why?
