A7R3 sometimes doesn't recognize lens after changing lenses

Why does this happen? Sometimes after switching lenses on my A7R3, the lcd screen is showing a flashing F-- number and both thes screen and the viewfinder are dark. Today it happened again and my usual method of turning the camera off and back on and/or un mounting the lens and re attaching it weren't solving the problem. That sometimes works but not today.

What was different this time is that I could set the camera for aperture priority and it would function as it should, but switching to shutter priority the problem came back.

After repeating these "tricks" it eventually started working as it should. What causes this, and is there a repair in my future or is this just a bug of some sort? Is there something I can do to make this problem go away for good?
