Server builds fine, but crashes saying "StructBox" is not enabled

MY project has an actor that uses StructBox arrays in blueprints, and everything runs just fine in standalone mode from the editor, and packages fine for both windows and Linux, however when trying to run dedicated server on my remote Linux machiene, the console crashes giving this error:

0]LogGenericPlatformMisc:Warning: Cannot display dialog box on this platform: Message : Plugin ‘StructBox’ failed to load because module ‘StructBox’ could not be found. Please ensure the plugin is properly installed, otherwise consider disabling the plugin for this project.

I have StructBox enabled on my project, and I have regenerated the project files both by right-click selecting “Generate Visual Studio Project Files” in File Explorer on windows, and from within the editor itself, but the same error comes back. Is there a step I’m missing?
