Prop Hunt template problem

Hello everyone
I’m currently making a prop hunt map using the template and tutorial provided by EpicGame. However, I’d like to know if it’s possible to recover only the system part of the template. That is to say, the various devices with the correct settings, the verse scripts, everything that’s necessary just to make the map work, because I’ve followed the tutorial in its entirety, but I’m encountering numerous problems when launching the game to test my map (no attributed classes, no timer countdown). I’ve spent several hours trying to solve the problems I’m encountering, but unfortunately I can’t do it. For example, I’ve tried copying and pasting the “game” folder available in the presentation map, which is functional, and putting it in my map, but it doesn’t work. I’m not at ease with the world of coding, which is why I’m turning to you for help. I’ve also read that the version of the tutorial available on the epicgame site isn’t up to date and I’d like to know if there’s an updated version.

I thank you in advance for your reply and wish you an excellent day.
