No output session in log.

Include a log file if you have a problem: here's how

To upload a log file, go to the Help menu -> Log Files -> Upload current/last log file. The current log file is for the currently active running session. The last log file is for the last time you ran the program. We recommend always including it just in case.

obsproject.com

Open OBS. Start an output session (streaming or recording). Observe your issue. Stop the output session. Upload the Current log without quitting OBS.

In general, though, OBS is not just a screen recorder, it is a video compositor and switcher, and it uses more resources than other software that lack those features.
