Logs show significant internet connectivity issue. Every streaming attempt fails due to network issues, it's only a question of when:

13:11:05.027: Max audio buffering reached!
It tries to keep reconnecting and can't-- the network is unavailable.
The source "background motion" is also now unavailable and causing the audio buffer to max out.
13:11:07.640: coreaudio: device 'UMC202HD 192k' disconnected or changed. attempting to reconnect
Looks like the audio interface was disconnected, or else the system is now so overloaded that the device is not responding.

At this point it seems like OBS can't even perform basic frame rendering. At this point you're probably having to force quit it.
I can't be sure if the network issue is a cause or a symptom. If your scenes are simple and can be recreated, it may be useful to archive and then delete this folder:
~/Library/Application Support/obs-studio
and start over and see if that improves the situation.
