Contact your sales representative to get detailed understanding about your license terms. If you don’t

know who your sales representative is, MathWorks support can help you find your sales representative:

This is not (directly) a licensing problem: if it were then MATLAB would have displayed the license error.

This is much more likely to be an installation difficulty, especially with regards to MacOS Catalina.
