Geometry script mesh disappears after package

Hello everyone,
I have a project where I dynamically generate building SMs with the Geometry Script plugin.
Everything works fine in the editor in “Play” mode but when I package my project, the building meshes generated by the plugin simply do not appear on the screen.

Do you have any idea where this could come from?
(I specify that I have version 5.3.2 and i package for Windows)
