Astra, Unity, orbbec_xs.dll caused an Access Violation

I set up a new Astra on a Windows 10 machine yesterday and everything seemed to be working fine. Last night Windows insisted on updating to the Fall Creators Update (not sure if this is relevant) and today whenever I run the Unity test scene it crashes the editor. Looking at the crash logs I can see orbbec_xs.dll caused an Access Violation and looking at the editor logs shows this to be the point at which the crash occurs:

ERROR: SymGetSymFromAddr64, GetLastError: 'Attempt to access invalid address.' (Address: 00007FFFF4FC2EB8)

Any ideas?

OK, contributing to answering my own question here.

I tried making a build of the test scene since the AstraUnity554Sample wasn’t exhibiting the same crashing behaviour. The build failed with an error Plugin ‘orbec.dll’ is used from several locations and Plugins colliding with each other so I tried removing Assets/Plugins/x86/OpenNI2 and Assets/Plugins/x86/Plugins. After that my build completed and the editor no longer crashes as frequently.
