Could you post the full log files for when your packaging fails? You can find the logs under Saved/Logs inside of your project’s directory. Also, have you done anything in this project related to the ScriptGeneratorPlugin, such as trying to add a dependency for it?
We haven’t heard from you in a while artoculon. Are you still experiencing this issue? If so, could you provide the information I requested in my previous comment? In the meantime, I’ll be marking this issue as resolved for tracking purposes.
