Deploying unity 3d app to hololens apps fails with code -2147483645

I recently upgraded my unity 3d app from unity version 5.6.0 to 5.6.1 and holotoolkit-unity from 1.5.6 to 1.5.7.

Now, whenever I build the app and attempt to deploy it to the device via Visual Studio 2017, I get the following error:

The program '[3492] LabanotationAR.exe' has exited with code -2147483645 (0x80000003).

IF anybody could give some pointers in how to go about debugging this error message, I'd really appreciate it.

This was a Unity issue fixed for a future release. This should be releasing in the next Beta update.
