Thank you for this amazing tutorial!
I did run into an issue while doing this (primarily because I was on UE 5.2.1) and here is the repository I used to fix the errors (as of July 20, 2023): New Repo by IDI-Systems
Another change I did was I added the Public/Private Dependency (found here) before I compiled the project, just as a safety measure, and then I Generated the VS Files.
