Technically it looks like Studio is crashing in the RTMP portion of code... which would make sense given that you're streaming when the crash happens. As to a fix... Could be a few things:
1. Try updating your NIC drivers.
2. If you have a KillerNIC uninstall all their crap and install just the clean drivers. (

3. Check and see if your anti-virus/Internet Security software is screwing with OBS.
4. More info (like an actual proper log) would be helpful....
5. ...well actually that's it for now.
