First off, update to the latest version. Secondly, looks like you're using a laptop. Make sure you have OBS set to use your Nvidia card and not the integrated one.

How do I make it use my Nvidia card? Sorry I'm new to this stuff

Nevermind I got it to only use my Nvidia card but I still get the black screen

Currently that specific laptop appears to be having issues due to its unique video card setup. I'm not entirely sure what to do about it yet.
