why does my roblox studio crash when i use this script?

while true do
    path = game:GetService("PathfindingService"):ComputeRawPathAsync(game.Workspace.Start.Position, game.Workspace.Finish.Position, 512)
    points = path:GetPointCoordinates()
    game.Workspace.Points:ClearAllChildren()
    for i=1, #points do
        part = Instance.new('Part')
        part.Size = Vector3.new(1,1,1)
        part.FormFactor = Enum.FormFactor.Symmetric
        part.CanCollide = false
        part.Position = points[i]
        part.Anchored = true
        part.Parent = game.Workspace.Points
    end
    wait(0.1)
end

my roblox studio crashes when i use this script. everytime i try to move my finish to a different position or add a part my studio crashes. why?
