Exporting to movie crashing Animate

I wanted to achieve a crayon look, as if it's a child's drawing, so I used the "chalk" art brush. It immediately slowed my computer down, but what's worse is that it literally cannot export to an image sequence. It takes dang near an hour to just crash on me, exporting between 10-25 frames. Is there a way to export this file fully??? It's a commission, so it's really screwing me.

Computer is a '17 Imac with all the memory ports filled. Should be capable of doing this.
