does this actually happen

local UserInputService = game:GetService("UserInputService")
local i = 0

UserInputService.InputBegan:Connect(function(input)
while input.KeyCode == Enum.KeyCode.Space then
i = i + 1
print(i)
end
end)

yes indeed. sometimes, when creating any type of game, your computer can get a BSOD. this happens when you have too many apps running, or for no absolute reason.
