Actor from plugin is broken after packaging (but works in editor)

I’m trying to use this plugin, here’s what I did. GitHub - FreetimeStudio/PortalPlugin: A collection of portal mechanics. This repository might occasionally be updated but there is generally no support for it.

I was able to rebuild this project in 4.19 and it works but I needed the VR template pawn. So I copy pasted the content from the project to a new VR template project created with 4.19. It works in the editor but when I package the map, the effect is broken. I need your help! Thank you.
