The reason is likely how you set up the aircraft which prevents VNAV from engaging according to real world logic of the systems. Have you changed something in operating the plane? Are you doing anything differently than before? I don't know of any bug in the NGX that would prevent VNAV engagement and there was no update to the product/nothing was changed from the developer's side, which is why it's probably user related.

In any case, we need some more information. In what situation does it not engage? How did you set up the aircraft?

Most likely your elevator axis is not centered and you have not configured the 737 to disable real-world autopilot connection behavior.
