It is still a premiere issue. vRender is Premiere.. everything right from it voukoder.
btw, please don't copy logfiles as images. There is a button "Copy to clipboard."
Did you ask the Adobe support?
I have not yet contacted support. I'm more confused by the fact that Nvenc didn't work on my system from the nvenc4everyone. But in some cases I managed to load the GPU by 30-40% with both your software and Nvenc. Trying to gather more information.
