Game crushes after binding new hotkey to "select ally"

It happened when i bind a new hotkey to "select ally 1"(hotkeys>camera control), then I can not move by right click. I noticed that the game was not completly crushed because everything else worked just fine. Also if I hold alt or ctrl, I can move by right click. I tested on 3 computers, so it is not my computer's fault. Sometimes it happens to "select ally 2/3/4" instead of "select ally 1".
