Add-on Error?

Hello, community! I was creating a new game and I encountered an error when trying to add a module add-on. Can anyone help? Here's a screenshot: Thanks!

As for the issue at hand, have you already tried to re-add it in a brand new game, outside of this one, to see if the issue occurs again? If so, what were the results? If not, can you please do that now and let me know how it goes? Thanks for your patience! It happened on 2 different games including a fresh from scratch game. Eventually, it stopped and I haven't made a new game after it stopped. I guess it was a glitch. Thanks for responding.

I even just tried it again just now and it worked fine. Weird. The same thing was happening to me with the API scripts before and then it just worked. Thanks for checking in.
