Preview unavailable for NEF files Nikon D780

Library->"Import" resulting error:

The Import dialog shows thumbnails for JPG files, but all NEF files show "Preview unavailable for this file"

Nikon D780 - Shooting RAW + JPG*

USB C cable directly to Windows 10 PC

LrC version 12.0

For comparision, all NEF Import previews work fine when plugging the same SD card in with a dedicated SD reader.

Are there any setting changes I can apply to Windows, LrC, or the camera to resolve this issue?  Thank you!
