Game Crashes due to HP Code

[ShmingDings]

Im working on a rouge type game where you’re a hunter trying to live in the woods, but for some weird reason after I added the HP code each time to wolf goes into the proximity the game crashes. Could someone please explain how this is happening?

Check the Timer with the Switch at bottom right of the whole code.
