Dash System Being Weird

So there’s this dash system i was making but it is a little weird. for some reason whenever you dash fast enough it can get two dashes out of the player?

local uis = game:GetService("UserInputService")
local SS = game:GetService("SoundService")
local DS = game:GetService("Debris")

local player = game.Players.LocalPlayer
local char = player.Character or player.CharacterAdded:Wait()
local hum = char:WaitForChild("Humanoid")
local rootPart = char:WaitForChild("HumanoidRootPart")

local canDash = false
local dashDirection = ""

uis.InputBegan:Connect(function(input, processed)
	if input.UserInputType == Enum.UserInputType.Keyboard and not processed then
		if input.KeyCode == Enum.KeyCode.W or input.KeyCode == Enum.KeyCode.A or input.KeyCode == Enum.KeyCode.S or input.KeyCode == Enum.KeyCode.D then
			canDash = true
			dashDirection = input.KeyCode.Name
		end
		
		if input.KeyCode == Enum.KeyCode.Q and canDash == true and dashDirection ~= "" then
			canDash = false
			local attachment = Instance.new("Attachment", rootPart)
			local linVel = Instance.new("LinearVelocity", attachment)
			local part = game.ReplicatedStorage:FindFirstChild("Part"):Clone()
			part.Parent = workspace
			local multiplier
			
			if dashDirection == "W" then
				multiplier = CFrame.new(-1,-1,-20)
			elseif dashDirection == "A" then
				multiplier = CFrame.new(-20,-1,-1)
			elseif dashDirection == "S" then
				multiplier = CFrame.new(-1,-1,20)
			elseif dashDirection == "D" then
				multiplier = CFrame.new(20,-1,-1)	
			end
			
			--local at = hum.Animator:LoadAnimation(script[dashDirection.."DashAnimation"])
			--at:Play()
			SS.Dash:Play()
			
			part.CFrame = rootPart.CFrame * multiplier
			
			linVel.MaxForce = 99999
			linVel.VectorVelocity = (part.Position - rootPart.Position).Unit * Vector3.new(100,0,100)
			linVel.Attachment0 = attachment
			
			DS:AddItem(attachment, 0.1)
			
			task.wait(1)
			
			canDash = true
		end
	end
end)

Maybe don’t set canDash to true everytime a key is pressed otherwise it’ll just let you dash again if you press w multiple times
(if you do that don’t forget to set canDash to true initially at local canDash = false)
