Cannot reflect obs screen to zoom.

Thank you very much for your help.
I've been using it for a while now, but when I try to use the recording screen of obs, the obs symbol appears and the recording is not reflected.
The obs is still running.
Do I need to buy the paid version?

You may need to start the Virtual Camera in OBS.
