Question / Help Black screen on startup and "starting the output failed. Please check the log for details."

Hi all, I'm trying to use OSB to record game play footage from my Acer laptop, Nvida Geforce 940M. It sets up fine, but when I open OBS, I see a black screen, not my desktop, and when I press "start recording" I get:
Starting the output failed. Please check the log for details.
Note: If you are using the NVENC or AMD encoders, make sure your video drivers are up to date.
here's the log:

If I go into settings, I think the issue is in the output tab: if I make the encoder Hardware (NVENC) the recording doesn't happen. If I make it Software (x264), I get a black screen with audio.

How can I get the video to record with the audio ? Is it not possible for me on a laptop ? If not, what software would you recommend I use so that I can get audio, game play, and face cam all recorded ?

Thanks for your help ! Sorry if I come off as a novice; this is my first time attempting to use software like this.

The 940m does not support nvenc.
You didn't specify what game you were trying to capture.
