1st log has no output attempts.

The second log has you trying to encode using NVENC while running OBS on the Intel GPU.

Your encoding settings have you trying to run NVENC on GPU 0, which is your Intel GPU. You can't do that. Either override which GPU OBS is launching on, or using advanced output mode and specify GPU 1 in the encoder settings.

Do you mean QSV?

If so, just so you know that's a different encoder that's not using your Nvidia card. QuickSync uses the Intel GPU built into your CPU, and will be providing lower quality at the same bitrate than your Nvidia card, especially since your Nvidia card is one of the newer ones.
