Project crashes music video

I am running the latest version of after effects and Premiere on this machine. I have been working between the two editiing a music video but mostly in after effects. My media Cache goes to one 4tb sandisk ssd while my footage is on another identical drive. I have edited the entire video, but now I have to color it and and titles. It craahses anytime I do any thing extra. when I try to color it it crashes. so I took the color out and tried to work on the titles and it started to act a little better, though still sluggish. but the more I do is the more it crashes. please help
