Command Line Build Fails During Setting Of Worker Threads For Enlighten

Hello,

When I build my project with the Editor open everything works fine.

When I do it from the command line, and look at the log, it fails consistently at the same point, and this is always what is at the very end of the log:

Refresh: detecting if any assets need to be imported or removed ... Refresh: elapses 0.039687 seconds (Nothing changed)
Setting up 4 worker threads for Enlighten.
Thread -> id: a50 -> priority: 1
Thread -> id: 32cc -> priority: 1
Thread -> id: 36b0 -> priority: 1
Thread -> id: 60c -> priority: 1
[Package Manager] Server::Kill -- Server was shutdown
Cleanup mono
Exiting batchmode successfully now!

This is on a Windows 10 Enterprise tower with decent specs. The command line args are:

C:\Program Files\Unity\Editor\Unity.exe
-projectPath
C:\Users\uy486d\Documents\Project
-quit
-batchmode
-executeMethod
HoloToolkit.Unity.BuildDeployTools.BuildSLN

(see https://github.com/Microsoft/MixedR...kit/BuildAndDeploy/Editor/BuildDeployTools.cs for build method)

In the log I see this towards the top:

GfxDevice: creating device client; threaded=0
Direct3D:
Version: Direct3D 11.0 [level 11.1]
Renderer: NVIDIA Quadro P4000 (ID=0x1bb1)
Vendor: NVIDIA
VRAM: 8083 MB
Driver: 22.21.13.8601

In the log of the Editor build, I see the GfxDevice has threaded=1.

Any guidance on what may be the issue here?

Thanks
