Water closet mold help

I’ve been getting mold on the ceiling and top of the walls in my water closet (private toilet room). I do not have an ac duct in the room, just a light with a suction vent. I did the toilet paper test on the vent and it sucked the paper on 3/4 sides, but the vent seemed a little dirty. There is no mold in the toilet tank or under it near the hook ups.
I’m kinda thinking it’s just humidity in my house from the ac blasting with the outside heat and the room has no air circulation. There is no other mold in the rest of the bathroom, closets or other areas.
Is this a common problem in south Louisiana? Should I look for any thing else? Get a moisture meter to see if there is water damage in the ceiling that is coming from the attic? (I kinda looked this afternoon when we had a little shower but didn’t see anything wet in the attic)
Clean it with vinegar and bleach then kiltz it and repaint?

I had the same issue due to lack of air circulation. I installed a small dehumidifier and problem solved.

Did you put the dehumidifier in the water closet itself or just in the bathroom?

I was having the same problem. Started keeping the lid closed on the toilet and that solved the problem.

I had this problem. I put a small fan in the corner blowing up at the ceiling. It circulates air constantly. No issues since.
