I can’t tell for sure from the pictures, but are you getting fish eyes in the paint?
I’d scuff the paint and apply a second coat. Often it’s best to spray a light coat first and then a final second for full coverage. From the pictures it looks like the paint didn’t fully bridge over surface grain in the wood. Second coat should eliminate that. If there is contamination like oils or silicone issue may still occur unless you use and additive like smoothie to break surface tension of the paint.
