SOS my cat won't poop in her box

I have an almost 5-year-old DMH cat who I've had since she was 8 weeks old. All of a sudden she has decided to stop pooping in her litter box altogether. She will poop right beside them!

I do have one other cat and three dogs, all of which we have had for at least 2 years. Her problem has started in the last 2 months.

We have three litter boxes spread out in a room that is baby gated away from the dogs. She will pee in her boxes but not poop.

I have cleaned the entire room with urine odor remover, mopped, cleaned and sanitized the litter boxes. After putting fresh litter in the boxes, she peed in one then pooped outside another one.

I've tried different brands of scoopable litter, scented and unscented. I'm at my witts end. Any help would be GREATLY appreciated! Thanks guys.
