Player teleports back to original position after weld destroyed

Player model is teleporting back to original position after destroying weld for my rotation script

SERVER SIDED SCRIPT

local event = game.ReplicatedStorage:WaitForChild("Rotationevent")
local StopEvent = game.ReplicatedStorage:WaitForChild("StopRotEvent")


event.OnServerEvent:Connect(function(plr, randomX, randomY)
local ISROTATING = true

StopEvent.OnServerEvent:Connect(function(plr)
	ISROTATING = false
end)

	
local function ROTATE(plr)
	local char = plr.Character or plr.CharacterAdded:Wait()
	local CANFLY = char:GetAttribute("Canfly")
	local sun = workspace:WaitForChild("SUN")
	local distance = (char.PrimaryPart.Position - sun.Position).Magnitude
	local duration = distance / 100
	local part = Instance.new("Part")
	local weld = Instance.new("WeldConstraint")


	part.Position = sun.Position
	part.Parent = workspace
	part.CFrame = CFrame.Angles(char.PrimaryPart.CFrame.Rotation.X,char.PrimaryPart.CFrame.Rotation.Y,-char.PrimaryPart.CFrame.Rotation.Z)
	weld.Part0 = part
	weld.Part1 = char.PrimaryPart
	weld.Parent = part


	local oldcframe
	CANFLY = false
	

	while wait(distance * 0.0005) do
		print(ISROTATING)
		if ISROTATING == true then
			part.CFrame = part.CFrame * CFrame.Angles(math.rad(randomX),math.rad(randomY),math.rad(0))
		else
			part:Destroy()
			weld:Destroy()
			CANFLY = true
			ISROTATING = false
			break
		end
	end
end

ROTATE(plr)


end)

Anyone know a fix?
