How to make a clone of the workspace without the game crashing?

Don't clone the workspace make a Folder inside of the workspace and put everything you want to copy in that and clone the folder instead.

ok let me rephrase it: how do i clone everything IN the workspace, assuming my game has like 4000 something parts inside of it without crashing(4000 * 2 = 8000 and 2 + 2 = 4; 4 - 1 = 3)

local Folder = Instance.new("Folder")
Folder.Parent = workspace

for _,v in pairs(workspace:GetDescendants) do
    v:Clone().Parent = Folder
    wait()
    end
end
