That only works if the cheat was made with code injection. (For example no reload)
What you need to do is you need to set the value of the address before you tick the freeze box. for example bg_jumpheight needs to be set to 1000 and then you freeze it so it doesnt change back.
About the crashing. Super jump is a little unstable. There are simple some places in the maps that you arent supposed to go. So when you get there the game crashes.
The addresses are still up to date.
