Player = game.Players.LocalPlayer
Character = Player.Character or Player.CharacterAdded:Wait()
HumanoidRootPart = Character:WaitForChild("HumanoidRootPart")
 UIS = game.UserInputService

UIS.InputBegan:Connect(function(input,gameProcessedEvent)
	if gameProcessedEvent then return end
	if input.KeyCode  == Enum.KeyCode.W then 
		HumanoidRootPart.Anchored = true

		end
end)

UIS.InputBegan:Connect(function(input,gameProcessedEvent)
	if gameProcessedEvent then return end
	if input.KeyCode  == Enum.KeyCode.S then 

		HumanoidRootPart.Anchored = true
	end
end)

UIS.InputBegan:Connect(function(input,gameProcessedEvent)
	if gameProcessedEvent then return end
	if input.KeyCode  == Enum.KeyCode.A then
		HumanoidRootPart.Anchored = false
	end
end)
UIS.InputBegan:Connect(function(input,gameProcessedEvent)
	if gameProcessedEvent then return end
	if input.KeyCode  == Enum.KeyCode.D then 
		HumanoidRootPart.Anchored = false
	end
end)

StarterGUI, localscript

But The Player could if they are falling press W or S and they would stop.

Since roblox uses ContextActionService for user inputs (a,w,s,d, arrow up, arrow down) you can disable them there. But there’s a few methods for going about it, such as:

local ContextActionService = game:GetService("ContextActionService")
local actionName = "CancelMovement"
-- // This will be used as a filler functions in this case
local function emptyFunc() end 

ContextActionService:BindAction(actionName, emptyFunc, false, Enum.KeyCode.W, Enum.KeyCode.S, Enum.KeyCode.Up, Enum.KeyCode.Down)

To remove this lock, all you’d need to do is ContextActionService:UnbindAction(actionName).
Additionally to what @km7dev Posted.

@Kitsomia But How do I Make it so You can also go left and right with the left and right arrow keys?

Personally, I’m a little stumped on this one, I tried to do some digging and context action service has :CallFunction() locked to only core functions. And I personally have not done this myself. You may need to create your own custom method for detecting a left and right movement for the right and left arrow.

A basic idea to get started could be running a render stepped function grabbing all current keys pressed to make sure the user is pressing either Left Arrow or Right Arrow keys game:GetService("UserInputService"):GetKeysPressed(). Then applying a force to the players humanoid root part (relatively how roblox does this) Humanoid:ApplyImpulse(Direction :: Vector3). You may need to experiment with this.
