krnl crashes roblox on second execution after joined in new server

I played roblox bedwars with a script it executes normally and works

but when i get into a second game where it leaves the server and joins a new one krnl is still injected so i can still execute scripts. But thats where i execute the script again in a different server same game it crashes. This also happens in other games for exaple for tower defense simulator if you use a autofarm script after game is done it automatically loads back into the lobby but it crashes in the loading screen for no reason.
