WP SMUSH PRO taking too long to smush images

Hello Guys, I have intalled WP SMUSH Pro a while ago, I tried bulk smushing images. It smushed 7 images out of 172 and then it stuck at 7 from an hour. I went through forum and as per the suggestion i deactivated cache plugin and added "" to trusted IP list in cloudflare but no success what should i do now?
