how do i stream reverse 1999 through OBS?

I'm not that familiar with OBS but I wanted to use it to screen record some game scenes to show to my friends later but I had trouble capturing the game on OBS. I'm using window capture and it worked except it's frozen on the opening scene but I could see my game cursor moving around but the screen won't sync with the game. Any ideas on how I could fix this? I never had this problem on my other games before, just with Reverse1999

OBS view is frozen on the opening scene
