There are several possibilities, one may be that you have the camera set to expose only if the scene is in focus. Trying to take an exposure prior to focus will result in a button push with nothing happening.

Maybe this D850 is too much camera for me.
Why won’t the shutter button work all the time? Why does it stop working. Works about 10% of the time. Have tried it on P, M, S, A modes.
Live view works every time all the time.
Ive switched lens from Nikon 24-70, sigma 50-500, fresh battery inserted
Does anyone know from my description?
