Advanced Sessions Plugin

I’ve seen some posts before that were having issues with packaged builds but nothing clear as to what to proceed.
I’m getting the error:
Couldn’t find file for package /Script/AdvancedSessions requested by async loading code. However I have no Script folder, everything is in the Plugins folder. I have a Blueprints only project. Also, everything works just fine in editor, it’s just on a package build that it fails.
Is there any way to fix this?
Thanks
