Does this only occur in this particular project or any project you try to package? If it still occurs in a brand new project, can you ensure that the plugin is being completely disabled? You can do this by right-clicking the .uproject file for the project and setting it to not being enabled from there, regenerate the project files, rebuild, and then try to package.
We haven’t heard from you in a while, Enol, Did you ever get to try what I suggested? If so, what were the results? Are you still experiencing this issue? In the meantime, I’ll be marking this as resolved for tracking purposes.
You guys seem to be pretty quick to issues as resolved (I guess you guys really have a lot of questions to keep track of.) I am actually experiencing this exact issue using 4.13.2 with a migrated project from an earlier engine version (4.11 I think) and I cannot seem to build – encountering the same error as Enol. I can try to provide more info if needed.
