Vive Focus 3, UE4 : stuck while building package after launch

[Dirk H]

Hi 

we started the getting started tutorial for Vive Focus development with Unreal Engine.

After pressing the Launch button the building process starts but after a while gets stuck and nothing more happens. UE Editors message "buidling...." keeps running

a SD card is installed, we are using UE 4.26.2.

From within the headset we can see that someting has been installed on the sd card under "settings, uninstall"
