Hexar AF Will Focus, But Not Take Picture

Just bought a Hexar AF Classic from eBay. Everything seems to be working correctly EXCEPT it won't take a picture. I've checked everything - it focuses, film advances, no issues in the menus, just no shutter action unless it's on self timer. I'm very new to photography and am still trying to figure things out so this could be a simple operator error.

Hmm ? Do you have film in it?

I do. Film is advanced as well.

Welcome to Photrio.
I've moved this to the sub-forum for 35mm cameras.
Hope you find the help you are looking for.
