How to fix no animation play ability?

Doesn't plays animation when died/reseted.

local Players = game:GetService("Players")
Players.PlayerAdded:Connect(function(Plr)
Plr.CharacterAdded:Connect(function(char)
    wait(2)
        local Hum = char:WaitForChild("Humanoid")
        Hum.BreakJointsOnDeath = false
        Hum:SetStateEnabled(Enum.HumanoidStateType.Dead, false)
        local anim = Instance.new("Animation")
        anim.AnimationId = "rbxassetid://4742312546"
        local DeathAnim = Hum:LoadAnimation(anim)

        Hum:GetPropertyChangedSignal("Health"):Connect(function()
                if Hum.Health <= 0 then
                    DeathAnim:Play()
                end
            end)

        DeathAnim.Stopped:Connect(function()
                Hum.Health = 0
                Hum:SetStateEnabled(Enum.HumanoidStateType.Dead, true)
            end)
end)
end)
