It was my very first try at Retouch and I was planning to start with a JPG file, this being the image I took especially to make sure the camera otherwise operated normally, which it did. I had the image on the screen when I made the attempt.
I am not familiar with the term/procedure you mention, "...lock the image". I may have locked it accidentally but not on purpose. How do I check on this, and if it is locked, how do I unlock the image?

I tried to duplicate your problem on my D5600 but couldn't. I even tried locking the image. I understand that the message you received is generic and is usually caused by a camera setting. Unfortunately, the exact setting causing the problem is not provided.
I'm not an expert on this camera. But you might want to look at the "recent settings" menu to see what you have changed that might cause this. Or, as a last resort is a factory reset in order?
