I've been gone for a few months and now my code doesn't work?

function highJump()
	script.Disabled = true
	local noid = game.Players.LocalPlayer.Character.Humanoid
	noid.JumpPower = 200
	noid.Jump = true
	noid.JumpPower = 50
	script.Disabled = false
end

local Player = game.Players.LocalPlayer
local Mouse = Player:GetMouse()
Mouse.KeyDown:connect(function(Key)
    if Key == "t" then
        highJump()
    end
end)

The purpose of the code above is to make a player jump very high when a button -- 't' in this case -- is pressed. It worked about 3 months ago but now it doesn't. Have there been any updates that prevent this code from working that I am unaware of? Also, I don't think it matters but the place I'm testing this in has FilteringEnabled set to true.

Here you go!

function highJump()

    local noid = game.Players.LocalPlayer.Character.Humanoid
    noid.JumpPower = 200
    noid.Jump = true
	wait()
    noid.JumpPower = 50

end

local Player = game.Players.LocalPlayer
local Mouse = Player:GetMouse()
Mouse.KeyDown:connect(function(Key) -- yeah idk how userinputservice works since i haven't used it in a while, but you can implement it later.
    if Key == "t" then
        highJump()
    end
end)
