I have been having the same problems,, it just shuts down for no reason at no specific point in time or with a particular video, totally random and only with the latest update.
I allow it to send error reports each time, hope it gets sorted soon its really annoying.
Edit ;
Try setting the stream output to 3 sec from 1.5 [seems to have worked for me]
GoTo > Preferences > Advanced Preferences > Stream Output > stream output mixer caching (ms) [change "1500" to "3000"]
Don't know how to upload pics to show you, hope that helps you navigate to it
Edit , Edit;
Maybe that didn't work.. seems to have returned to randomly crashing again today
