If the same error happens with multiple known-good Nikon lenses, the problem is very likely in the camera body, not the lens. Since charging the battery changed the symptoms and some controls also stopped working, this points to an internal camera fault rather than a setting you can reset in the field.

There isn’t a reliable quick fix beyond the basics: fully charge the battery, power-cycle the camera, remove and reattach the lens carefully, and try another battery if available. But if the error persists across lenses, the realistic answer is that the camera needs service.

Since Nikon agreed to repair it under warranty, sending it in is the right move. For the event, use it only if it behaves well enough to shoot, but don’t count on it being dependable.
