if i try to change a welds orientation it destroys it self how can i fix this?

if I try to change the orientation of the part it either does not work or the weld destroys itself is there a fix for this?

I heard u can use weld constraints I tried but I did not understand

-- grimoire code

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local EventFolder = ReplicatedStorage:WaitForChild("EVENTS")
local Remote = EventFolder.ActivateGrimoire

function GetGrimoire(player)
	local Char = player.Character
	local Hurmp = Char.HumanoidRootPart
	local DataFolder = player.Data
	local Grimoire = DataFolder.Grimoire
	local GrimoireName = Grimoire.Value

	if GrimoireName == "None" then
		warn("Player Does Not Have Grimoire")
	else
		warn(GrimoireName)
		local GrimoireFolder = script:WaitForChild(GrimoireName):Clone()
		local NewGrimoire = GrimoireFolder.Open
		NewGrimoire.Parent = workspace
		NewGrimoire.Orientation = Vector3.new(0,0,24)
		
		wait(.01)
		
		local NewWeld = Instance.new("Weld")
		NewWeld.Parent = Hurmp
		NewWeld.Part0 = Hurmp
		NewWeld.Part1 = NewGrimoire
		NewWeld.C0 = CFrame.new(0, -.5, -3)
		
	end
end

EventFolder.ActivateGrimoire.OnServerEvent:Connect(function(Player)
	GetGrimoire(Player)
end)

Sorry I don't know anything about this but maybe looking through this source code from a plugin can help( i didn't make this):

local plugin = PluginManager():CreatePlugin()
local button = plugin:CreateToolbar("GeomTools"):CreateButton("Transform","Freezes attachments for transformations","rbxassetid://606821411")
local mouse = plugin:GetMouse()

	-- arbitrary wait fixes everything
	wait()
	local part = p.Part
	local originCFrame = p.OriginCFrame
	local originSize = p.OriginSize
	local newCFrame = part.CFrame
	for _, a in pairs(p.Attachments) do
		local attachment = a.Attachment
		local attachmentOriginCFrame = CFrame.new(a.OriginalPosition) * CFrame.Angles(math.rad(a.OriginalRotation.X), math.rad(a.OriginalRotation.Y), math.rad(a.OriginalRotation.Z))

		local correctedCFrame = newCFrame:toObjectSpace(originCFrame) * attachmentOriginCFrame
		attachment.Position = correctedCFrame.p
		local x, y, z = correctedCFrame:toEulerAnglesXYZ()
