CFrame not updating

I made a monster that moves closer to you when you’re tabbed out of roblox, this worked yesterday, but it suddenly stopped working even though I haven’t changed anything.

I have tried using a pcall and added a print(“success”) at the end of the pcall, it reaches the “success” and yet it doesn’t update the cframe.

Here’s my code

		repeat
			local success, errormsg = pcall(function()
				wait(0.1)
				local PlayerHumanoid = monster
				local TargetHumanoid = game.Players.LocalPlayer.Character.HumanoidRootPart
				print(game.Players.LocalPlayer.Character.Name)

				local LastTargetPosition = TargetHumanoid.CFrame
				--- The CFrame below doesn't update
				PlayerHumanoid.CFrame = LastTargetPosition + LastTargetPosition.LookVector * Length
				PlayerHumanoid.CFrame = CFrame.new(PlayerHumanoid.CFrame.Position, Vector3.new(LastTargetPosition.Position.X, PlayerHumanoid.CFrame.Position.Y, LastTargetPosition.Position.Z))
				print("success")
			end)
			if not success then
				warn(errormsg)
			end
		until
		IsFocusedOnWindow or Length > -1
		if Length >= -1 then
			jumpscare:Play()
			errorsound:Play()
			script.ColorCorrection.Parent = game.Lighting
			game.Players.LocalPlayer.Character.Humanoid.Health = 0
			monster:Destroy()
			game.Players.LocalPlayer:Kick("An unexpected error has occurred.")
		end
	end)
	if not succ then
		warn(err)
	end

I hope anyone has a fix for this, it was working perfectly fine and now it suddenly stopped working.

Can you show the part where you are checking for the focused window? It could also be your Length variable, I am not sure how you are updating that.

Thanks for telling me that, I guess that line somehow got lost when I published the game.
Guess that bug exists in roblox.
