Considering how new this camera is, I'd be surprised if anyone else is having this problem, much less knows what's really going on, but I'll run it up the flagpole, and see what anyone might have to say.

I was messing around this morning, thinking I was going to use it as a webcam for a meeting. When I do that, I set the c3 "Power off delay" Standby Timer to "No Limit" to make sure the camera didn't go to sleep during the meeting. Then, prior to the meeting, I changed my mind, and decided to go a different route. I thought I had reset the c3 "Power off delay" Standby Timer to its usual setting of 10 minutes. I may not have. I thought I turned the camera off. I may not have done that, either. Don't remember.

When I went back to the camera several hours later, it wouldn't focus any lens, and in manual mode, I got the message, "Error -- Press shutter-release to reset." I did that, and the camera would shut off completely. I turned the switch off, then then it back on, and get a message that the shutter was closed, and to begin taking photos, I needed to press the shutter release. I did so, but the camera immediately shut off again. This went on and on, regardless of settings or lens. It lasted ever so slightly longer in Aperture priority or Shutter priority, but P and M were and over and done thing.

Without thinking to check the battery levels, I pulled the battery grip off, and put a known fully charged battery in the camera. Everything worked fine.

I replaced both batteries in the grip with known fully charged batteries, and put the grip back on the camera. 80+ images later, and everything is still working fine.

I put both batteries that had been in the grip on chargers. One charged relatively quickly, the other is still charging (it's been less than an hour).

Has anyone else run into anything like this with one of the new Z cameras? I would have thought that if both batteries had died, the camera would simply shut off and not function when turned on, but I suppose the batteries could retain enough charge to cause all this mayhem.

Well a battery problem is a lot less worrisome than a body problem.
Are all your batteries OEM and of the current generation?

This is only tangentially relevant, but I have several rechargeable batteries (probably about 5 years old) that I use in my mouse. It has been obvious for a while that their capacity per charge has been declining. And recently my bluetooth connection has been intermittent dropping. I put in some regular AA batteries and everything works seamlessly. My point is that batteries can get wonky and either produce spikes or drops that don't play well with digital circuitry.

Nikon batteries also contain, I believe, some digital circuitry that lets them 'talk' to the camera's hardware/software. It is possible that circuitry has partially failed as well. I've had this happen where the camera simply doesn't recognize the battery that previously worked.

All of my batteries are brand new Nikon EN-EL15c batteries.

After not experiencing this problem since my original post, it happened again this morning, but this time the camera actually shut down and would not turn back on. I finally pulled the battery grip off, put a battery directly in the camera, and tried turning it on. The camera fired right up, and behaved normally. I turned it back off, removed the batter, and reinstalled the grip. The camera come back on, and has worked perfectly since.

I got that same error message with my Z72, the FTZ and a 200-500 lens. It turned out the lens wasn't fully seated to FTZ contacts. I rotated the lens a little more and it works fine.
