Editor becomes unresponsive if Default Audio Device changed
Changing the audio device in Windows (or unplugging / replugging in a Jack) causes the editor to become completely unresponsive.
This is easy to reproduce - in my case I just unplug an audio jack on the back of my PC and swap it over to another one (E.g., switching between headphones or speakers). When I do this, the editor locks up completely and I can't interact with anything.
Nothing in the logs though, and Visual Studio still responds fine. This also occurs in Paragon.

There were 2 separate fixes for the win10-only issue. The first is in 4.13 now and should fix the issue with unplugging headphones while UE4 is running (it won't crash). The second fix related to win10 going asleep then unpluggin phones, and we found it right before 4.13 went out so the fixt didn't make it into 4.13 and is likely not going to make it in a hot fix.
The change doesn't look like it's in our UE4/Main branch yet.
