The Animator

Every once in a while before my drawing saves, the canvas and the tools freeze and when I try to refresh the page what I was working on disappears. If I had already saved the drawing and I go to edit it after that it asks if I want to clear the drawing before or keep it. If I press keep it, then how the drawing looked before the screen froze. If I clear it, it just looks how it looked when I saved it before.

It’s starting to get better but idk what happened before

Hdhwjhdhe it keeps happening

Is it a very large animation?

No, it freezes up even if I just have one frame.
