I am trying to build a barebones Unity HL2 project to my HL2 device (followed this guide point by point). However, whenever I try to deploy through Visual Studio, the PIN box that usually appears to connect the HL2 with my laptop doesn't appear (I've made sure my HL2 isn't already paired with the laptop). I've tried again with a whole new project and it hasn't worked then too. I tried resetting my HL2 completely, but that didn't work either. I've tried out most if not all of the fixes that are proposed in other forums and stack overflow posts, including changing my debug target to x64, ensuring Developer mode is enabled on the Hololens, and installing USB Device connectivity for VS.

I'm including the repository from github if it helps: it's a small repo, as again, it's just a barebones HL2 demo.

The error I get when I deploy is below.
