UserInputBegan won't run if user clicking on explorer's child

[Arethuxia (Aeloria)]

UserInputBegan won’t run if I clicked on explorer, I’m not sure if it’s an engine bug or my script bug

As you can see in the video I tried to block after clicking the child inside of the explorer and got back to the game pressing F key the input began won’t detect it even thought I tried to add Cancel and WindowFocusReleased

My script

local function startBlock()
	print("WO")
	if not Humanoid or Humanoid.Health <= 0 or debounce.Punch or isBlocking then return end

	isBlocking = true
	RemoteSkill:FireServer("BlockStart")
	animBlock.Looped = true
	animBlock:Play(0)
end

UserInputService.InputBegan:Connect(function(input, gameProcessedEvent)
	if gameProcessedEvent then return end 

	if input.KeyCode == Enum.KeyCode.F then
		startBlock()
	end
end)

Even the print WO won’t run after I clicked on the explorer’s child

Expected behavior

InputBegan detecting keys while checking properties of a child in explorer

It’s because when you have something selected, “F” becomes focus.

If you turn this option off, it will work fine.
