A few years ago, the Roblox grow script worked normally. Nowadays, after dozens of updates, the script no longer works. I have already made modifications that fixed the error in the console, but fixing the error did not allow it to work.

The script is here:

--// Made by "failedmite57926" //

--// variables //
local LocalPlayer = game:GetService("Players").LocalPlayer
local Character = LocalPlayer.Character
local Humanoid = Character:FindFirstChildOfClass("Humanoid")
 
--// function //
function rm()
    for i,v in pairs(Character:GetDescendants()) do
        if v:IsA("BasePart") then
            if v.Name == "Handle" or v.Name == "Head" then
                if Character.Head:FindFirstChild("OriginalSize") then
                    Character.Head.OriginalSize:Destroy()
                end
            else
                for i,cav in pairs(v:GetDescendants()) do
                    if cav:IsA("Attachment") then
                        if cav:FindFirstChild("OriginalPosition") then
                            cav.OriginalPosition:Destroy()
                        end
                    end
                end
                
                v:FindFirstChild("OriginalSize"):Destroy()
                
                if v:FindFirstChild("AvatarPartScaleType") then
                    v:FindFirstChild("AvatarPartScaleType"):Destroy()
                end
            end
        end
    end
end

--// end //

I fixed the script errors as the console reported. Even after fixing the problem, it still persisted, but now without any console errors.
