I'm trying to use OBS but whenever I broadcast, every 10-20 seconds, the screen will turn black for a half second or so when my game is open. I saw the sticky thread but that's for if your stream is flashing black, not your actual screen.

I am using a laptop with a nvidia gpu

log from last broadcast:

Let's see a video of it. If you're capturing a fullscreen game with something other than game capture you're probably going to experience issues, but I don't specifically know what you're doing.
