followed a step by step tutorial, made sure I did everything right yet got an "Aborting launch due to failed build" message form the console

I have a garmin venu 2 which I tried the following guide on.

I followed a step by step by a tutorial about font changing from 2016 (https://www.youtube.com/watch?v=PRQyA4BeqqE) and in 6:53 when the guy ran the project he got a black screen and I can't run it and the console writes: "Aborting launch due to failed build." I changed everything by the API changes ( Gfx -> Graphics; Sys -> System; Ui -> WatchUi) yet the problem is still there. can someone help me understand the problem? I'm kind of a newbie with the connect IQ and having a realy bad time trying to create a watch face in the last few days. I'm adding the file in hope someone can help and really hope it doesn't take a lot of work and effort doing this.

TY in advance!!!
