I attempted to make a script so you drop tools by pressing "G". Why does it work on Studio only?

I didn't want to make my weapon drop by backspace, because the player would still be holding the tool (I welded the tool). So I made a script and placed it in StarterPlayer>StarterCharacterScripts and this is what the code looks like.

local character = script.Parent

function onKeyPress(inputObject, gameProcessedEvent)
    if inputObject.KeyCode == Enum.KeyCode.G then
        for _, child in ipairs(character:GetChildren()) do
            if child:IsA("Tool") then
                child.Parent = workspace.Drops
                child.Handle.CFrame = CFrame.new(child.Handle.CFrame.X, child.Handle.CFrame.Y + 5, child.Handle.CFrame.Z)
            end
        end
    end
end

game:GetService("UserInputService").InputBegan:connect(onKeyPress)

So whenever I press G while holding a tool, it should get everything inside the Character, find any tools inside the character, and if there is one, it should change the parent to workspace.Drops which is a folder, and move the tool 5 studs above the player. Like I said, it works on Studio, but not on the ROBLOX Client. Any things I could change in this script? Or I did it completely wrong?
