Actors who quit acting to do something else

Jenny Wright quit acting in the 1990s. She was best known for playing the female lead in Katherine Bigelow's Near Dark (1987). In the mid-2000s images of her and a team of people trying to save farmland appeared on social media. They needed money for a new tractor (if memory serves) and were asking for donations. Jenny Wright did a few ironic hollywood-style poses (in dirty work clothing) for the camera to get people to donate.

According to IMDb she now makes appearences at horror conventions.

I will always remember her in I Madman.

Rick Moranis was one of the big names in humor in the 80s.  When his wife died, he "took a break" from movies so he could better raise his kinds and never went back to it.
