Spawnicons and some tools crash game.

Hey guys recently, when im searching for a prop it will crash my game completely, i dont really know the cause of this, but it also happens using some tools, eg button tool, i assume because this makes spawn icons and that, but some things like wire values crash too, if anybody has any idea whats causing this please leave a reply. and also i dont crash much so if you tell me where to pick up a crash log ill grab it and put it here, thanks.
