I have created a minimal Unreal project using the starter content. I have generated signing certificates, and successfully packaged and run the project on the Hololens 2 emulator.
However, when I try to package the same project for my device, I get a the following failure:
UATHelper: Packaging (HoloLens): Using ARM64 architecture for deploying to HoloLens device
UATHelper: Packaging (HoloLens): ERROR: No required compiler toolchain found in C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.27.29110

UATHelper: Packaging (HoloLens): AutomationTool exiting with ExitCode=6 (6)
UATHelper: Packaging (HoloLens): BUILD FAILED

How can I not have the required compiler toolchain on the device, but it succeeds in the emulator? What steps do I take to get around this?
