How to add working rnp arrivals/ils approaches?

How can I add custom rnp/ils arrivals to airports? I tried to follow this tutorial MSFS - Coding xml SIDs/STARs/Approaches - A small tutorial | FSDeveloper , not sure if the tutorial works anymore in 2022 since the waypoints don’t show up in game and the approaches show up in menu without waypoints, but pressing the approaches and pressing fly causes the game to crash. any help?
