Getting too much time to render

Hey dear developers!
I’m using After effects in Macbook pro to create Lottie files.

  1. When i press the render button getting too much time to render and my mouse point turn to the loading cursor (watch icon) in all the screens not only in the After effects window.

  2. also when i click the cancel button it won’t work too

This is an awesome product for the future website and applications btw keep this up!
