Can't package project due to plugin Unreal 5.3, why?

Hello, I’m having trouble packing my project due to a plugin I have.

The plug-in is a dialogue plugin so it’s vital to how my game works. However, it causes issues in my packaging. I’m still new to unreal and I’ve tried to google what specifically is missing and what I need to do. However I still haven’t come up with a solution.

Cheers
