Prop hunt ERROR

Hello EPIC community! I’m trying to create a system that generates random teams for my Prop Hunt project. I’ve tried using the devices, but nothing works as I want it to. I would like a distribution of 20 Props and 4 Hunters, randomly assigned each time, or an equivalent distribution with more players but never fewer. I also tried using the Fortnite tutorial available to players, but when I download it and add it to my project, it doesn’t work as described in the tutorial because it doesn’t launch. For those familiar with this tutorial, I think the issue might be related to the cinematic? But I’m not sure. I would really appreciate any help on this, and I’d be extremely grateful.
