LR Classic 12.5 - Tethered shooting not working for Nikon D700
I'm using Windows 10. If I connect my Nikon D700 to my PC via USB, Windows detects the camera just fine, in that it gets mounted as a removable storage drive and I can navigate into de DCIM folder and see NEF files in the memory card. But if I try to tether the camera using LRC 12.5, it gets stuck trying to tether, displaying the dialogue shown below without ever resolving.

I've tried different USB ports and cables, with the same result (camera always gets detected by Windows 10, but never tethers to Lightroom).
This is a pretty big problem for my shooting workflow so I'd appreciate some help getting this issue solved.
Thank you
