Newbie question

Hi,
I have been using OBS for a few weeks to stream our church service. We have a single USB camera (Sony HD) connected via a hdmi grabber. Audio is via Presonus iOne. First week OBS was used on macbook before switching to windows laptop. This morning after 5 minutes the video went black and I could not find what went wrong. My theory is that OBS video crashed because OBS would not shutdown. All through the live stream there were pop-ups saying OBS using webcam. Which it wasn‘t as far as I could tell. Kaparsky was the only other program running.
I have two questions:
1. What should I have done to get the stream live once more?
Resetting scenes all worked except for video.
2. If I rebooted the system mid send can I carry on after reboot, or would youtube have closed the stream?

Where do I find the logfile?

Thanks for any help.

That does sound like a crash, yes.
1. You could probably have gone into the Windows Task Manager, to find the 'hung' OBS process still-running and end it, rather than rebooting.
2. That would be a question for YouTube. If they require you to get a new key for each stream, it is likely you would need to get a new one; a crash will definitely end the stream.

As far as what caused the crash, it could be any of a number of things. You can go into %APPDATA%\obs-studio\logs and find the one with the date/time stamp from the start of that session, and take a look inside. But we'd really need to know what was happening immediately before the crash, to get a clue. If a scene change just happened, or if you turned a source on or off, adjusted a volume level, switched cameras through a switcher hub, anything like that.
Crashlogs are in %APPDATA%\obs-studio\crashes, but usually a 'hung' situation will not generate one of those, if the program just freezes and doesn't fully crash-exit.

Spitballing:
-Could have been a GPU crash, but those tend to make the whole system blackscreen briefly.
-Could be the HDMI Grabber bugging out. If it sends bad-enough data, OBS can get 'confused' in not knowing how to handle it, and be unable to recover gracefully.

Thanks,
I was back at church yesterday and have uploaded the logfile.

When we tried it afterwards it just worked - of course.
