Hi,

unfortunately there is no information about why the process stops. It stops at the end of the build process. So even before it is loaded on the HoloLens. I don't think the problem is HoloLens specific. Maybe it is due to the architecture (ARM64) of the UWP.

I deleted one component at a time and after deleting the "game4automation\private\Interfaces\OPCUA4Unity" folder, the build process worked. The problem seems to be in the OPCUA interface.

Best regards
