HELP! Can't Recording fortnite with obs

Hey guys I got a question why can't I do game capture to record fortnite? only works in windows mode but my pc fps drops for some reason in windows mode and I can't play. does anyone have any ideas how you can make it with game capture? I did try to add all 3 of the options but for some reason my OBS just doesn't see the fortnite game

Happened to me a bit but it fixes itself after a while.

I use Game Capture and use any app/game in fullscreen while also having fortnite in fullscreen. There will be a black screen on ur obs for a few minutes/seconds but it will fix itself.
FYI: This is how I record, may not be the same for you.

Doesn't work for me, could be the problem that I play from notebook?
