Why do I receive MathWorks Licensing Error 5?

I have a subscription for doing cources online till some time in 2026, and I should not be getting this error.

I am trying to open a course with Mathworks online, for which I have a paid subscription.

I recommend checking with the administrators of your license to ensure that Simscape Multibody is included in your license and that not all the licenses are in use.

As an analogy to a library book, you can't take it out from the library if your library doesn't own a copy (ignoring inter-library loan for purposes of this analogy) or if all the copies of the book the library owns are checked out by other patrons.
