Render Queue and Background Rendering not working

[bakutislinas]

Hi guys,

I've recently upgraded to newest Keyshot version and some issues started to come up.
In some files Render Queue and Background Rendering is not working (default rendering works, also mentioned features works in other KS files).
I'm attaching screenshots. Maybe anyone has any idea why that is?
Renders that are already added to Queue also not running when processing queue from KS file in which everything works (so issue should be with file itself?).
Render window pops-up and closes after a second or so. Everything was working in KS 8 before update.

CPU rendering.

Thanks so much!
