Differences from final render (F12) to rendered viewport

[bardo]

In a testing scene I've, I found a big difference from the final render and the rendered viewport.
This is the final render

And this is the rendered viewport

What should be the reason? I know it's difficult without the scene.
The log file in the "Temp" folder could be useful to track this?
The log file in the attachments

EDIT: I'm using the 169 version, but it was the same with the older ones.

Thanks for the report. Within the log file, I can see errors concerning the lights in the scene. It would be amazing if you could provide a very simplified version of the scene that displays the issue so we can investigate further.

I'll try to do what you requested.
Meanwhile, testing with v177, I have this

On the left the final render (F12) and on the right viewport rendering.
There is something missing both on lighting and white balancing....it seems.

Anyway, I'll try to make a simple version of this file.
