Wait! You can't just press Render Animation

It is a dramatization maybe 1 or 2 at one time but each one at last once.

Also, use Eevee render if you dont already. Cycles’s marginal quality advantages often arent worth its absurd render time. Especially for cartoony animations

The concept still applies. There is nothing blender can do to stop this, you have to be systematic and careful to reduce extra work.
