What does this log error mean?

I'm using BYN 2.1.2, premium. I've posted a couple of times lately about various errors that ended the imaging session with my older D810A. I believed, and still do, that the problem was the data cable port on the camera, due to minor cable snags and age. I emailed in a log (with a link to my forum post), but have not heard back. I recently replaced the older camera with a brand new D850, which I had astro-modified. Over the course of an hour or two of imaging, a "camera shutdown" will disconnect the camera and end the imaging session more than once. I initially thought the camera might be set to put itself to sleep, but that makes no sense in light of the fact that it's on AC power and is actively imaging. Also I can immediately reconnect without going out to do anything with the camera. The log is giving me this error, which I don't understand:  "Object reference not set to an instance of an object." Can anyone help me make sense of this?

Still, the mini PC could have an under-powered USB design. Have you tried the new camera with a different computer?

I have not. But I have exactly the same make and model computer upstairs and do not have the problem. Still, I will look into what you suggest.

Catherine,

A web search found the following page: https://www.iconasys.com/camera-settings/nikon/d810a-camera-software-settings/. Step 5 reads as follows:

5. If your camera has Auto Power Off or Auto off Timers (in the  Timers/AE Lock Menu) please set these to Off or Long

This may be worth checking.
