Program freezes

Hi. My Principle crashes about scrolling a page. I am trying to animate a rather long web page. Can you help me, please!

  1. check for macOS updates
  2. check for Principle updates. The latest version as of right now is 5.9.
  3. Does it crash on other files? If not, the document you’re working on may be more than your computer can handle. try reducing the number of layers and large image/videos you’re using. you can drag layers from the layer list onto the canvas to flatten if and all the child layers into a single layer. that trick can be used to reduce the number of layers.
