Unity editor freezes when playing, i think it's the loops

I'm trying to make a loop, what it does is it'll generate a number, and then checks if the number(ID) is disabled or not if it is it'll loop and makes one again. the thing is that it has a break when the generated number is not disabled, so I'm guessing the loop couldn't find the number and keep looping infinitely?
