How do I get my aim script to work after death?

I tried to make a simple third person aim script where the character faces where camera points, but after the character dies the script doesn't work anymore. How can I fix it? Any other way of creating an aim script? Any help is appreciated.

AIM SCRIPT I TRIED

local userInputService = game:GetService("UserInputService")
local UserGameSettings = UserSettings():GetService("UserGameSettings")

userInputService.InputBegan:Connect(function(input)
    if input.UserInputType == Enum.UserInputType.MouseButton1 then
        UserGameSettings.RotationType = Enum.RotationType.CameraRelative

    end
end)
userInputService.InputEnded:Connect(function(input)
    if input.UserInputType == Enum.UserInputType.MouseButton1 then

        UserGameSettings.RotationType = Enum.RotationType.MovementRelative


    end
end)

userInputService.InputBegan:Connect(function(input)
    if input.UserInputType == Enum.UserInputType.MouseButton2 then
        UserGameSettings.RotationType = Enum.RotationType.CameraRelative

    end
end)
userInputService.InputEnded:Connect(function(input)
    if input.UserInputType == Enum.UserInputType.MouseButton2 then

        UserGameSettings.RotationType = Enum.RotationType.MovementRelative


    end
end)
