it doesn't crash when you just run it once. It starts to freeze (and eventually) crash if the command is run often.
- Try putting the function in a 'needs redstone' repeating command block with a comparator attached to it which reads the output of a hopper chain.
- Then throw an item in the hopper chain (so the comparator turns the command block on for a few ticks),
- you'll notice the fps gets less and less,
- and eventually it's crash (if you do this twice in a row, for example)
