Error Packaging Hololens 2 Mixed Reality Tools Project

Hey everyone,

I was watching and following along with this demo Hololens 2 project:
Youtube - ´Create a HoloLens 2 app with Unreal Engine and Mixed Reality UX Tools | Inside Unrealstrong text´

Unfortunately, everytime I try to package the project, I get the error pasted below. Even though I did everything as in the video… Would be great if somebody could help me out with this!
