Unity play mode crash - Insider preview 16257
Hi. I'm experiencing a crash when starting play mode in Unity since updating to insider preview 16257. As soon as the Mixed Reality Portal starts up, I get this error from Microsoft Visual C++ Runtime Library: "Runtime Error! Program: The application has requested the Runtime to terminate in an unexpected way."
Tried Unity 2017.2.0b4 & 2017.2.0b7, same crash.
Acer headset driver 10.0.16265.1000
Recently set up controllers, though I'm experiencing this both with controllers paired and unpaired.
