I have a few questions for you that will help narrow down what issue it is that you are experiencing.
Quick questions:
Can you reproduce this issue in a clean project?
If so, could you provide a detailed list of steps to reproduce this issue on our end?
Can you provide screen shots of any blueprints that may be involved with this issue?
Could you provide the exact error that you receive when trying to package?
I would like to point out that I did try enabling the plugin in clean project and I did receive a failure to build. However, I did not receive an error message like the one in the post that was linked.
I noticed that you built using the Development configuration instead of Development Editor. Could you try building the Engine in Development Editor and let me know if you still receive this error?
