Door tweeining opening issue

[RetroAmythest]

1. What do you want to achieve? Keep it simple and clear!
   I would like to fix my door opening tween script.

2. What is the issue? Include screenshots / videos if possible!
   Some parts of the door go weird when it rotates. Also my door is a model and it is all anchored with no welds and it is placed on an attachment (For my placement system) and it rotates around the attachment. Here is a video of my issue happening :
   

3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
   I have looked for solutions on DevForum and on YT and tried ChatGPT but still nothing.

Here is my code :

local TweenService = game:GetService("TweenService")

local clickDetector = script.Parent

local model = script.Parent.Parent.Parent

local attachmentPart = clickDetector.Parent

local doorSound = attachmentPart:WaitForChild("DoorSound")

local attachment = attachmentPart:FindFirstChild("DoorSnapAttachment")

local primaryPart = model.PrimaryPart

local tweenInfo = TweenInfo.new(
	1,
	Enum.EasingStyle.Linear,
	Enum.EasingDirection.Out,
	0,
	false,
	0
)

local open = false

local deb = false

clickDetector.MouseClick:Connect(function(player)
	
	if model and attachment then
		
		if deb == false then
			
			local attachmentPosition = attachment.WorldPosition

			doorSound:Play()
			
			deb = true
			
			if open == false then

				open = true

				for _, part in ipairs(model:GetDescendants()) do

					if part:IsA("BasePart") then

						local currentCFrame = part.CFrame

						local rotationCFrame = CFrame.new(attachmentPosition) * CFrame.Angles(0, math.rad(90), 0)

						local goalCFrame = rotationCFrame * (currentCFrame - attachmentPosition)

						local tweenGoal = { CFrame = goalCFrame }

						local tween = TweenService:Create(part, tweenInfo, tweenGoal)

						tween:Play()
					end

				end

			else

				open = false

				for _, part in ipairs(model:GetDescendants()) do

					if part:IsA("BasePart") then

						local currentCFrame = part.CFrame

						local rotationCFrame = CFrame.new(attachmentPosition) * CFrame.Angles(0, math.rad(-90), 0)

						local goalCFrame = rotationCFrame * (currentCFrame - attachmentPosition)

						local tweenGoal = { CFrame = goalCFrame }

						local tween = TweenService:Create(part, tweenInfo, tweenGoal)

						tween:Play()
					end

				end

			end
			
			task.wait(1.5)
			
			deb = false
			
		end
		
	end
	
end)

I would recommend you welding the whole door to one invisible part and then rotating that specific part instead of every part in the model
