While you’re animating, try to save your progress every 2 minutes before your program crashes (if it does). That way, when it crashes, you won’t lose much progress. It’s also useful when you are finished and want to export. That way, your file won’t get corrupted and you will have most of your data and sometimes you can go back to where you left off!

If this is unhelpful or it doesn’t work at all even though you used the tip I gave you, please PM me.
