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.

  • Yes, was previously working. Will try updating GPU driver and post back.

  • That seems to have worked! Thank you!

    As a side note, I'm now getting a steady stream of the following error, also new. Any ideas?

  • Hum.. Have you installed the Windows SDK for Insiders?

  • I have. Has it been updated since 16257 was released?

  • GPU driver update seemed to fix this for a moment, then came right back.

  • I've installed the latest version of the SDK for Insiders but the problem persists.

  • Hum maybe @Jesse_McCulloch have some ideas?

  • I think 2017.2b8 will make this go away. I'll warn you that there is an issue with rendering in 2b8, the end result being a short draw distance.

  • By short, we are talking the above 20m clipping issue, right?

  • Yes. In the MR250 app we presented at build you can't see the volcano from your starting point, and the rocket launch is pretty boring when the rocket disappears almost immediately after launching.
