Did you check out the links in the "See Also" on the right hand side of this page? If so and none of them worked, the FAQ will definitely work:

Hey @gema
I understand you are facing licence related issues when trying to open MATLAB after an update.
A possible troubleshoot that worked for me was to uninstall and reinstall MathWorks Service Host. You can find the steps in the attached link.
How do I uninstall and reinstall the MathWorks Service Host? - MATLAB Answers - MATLAB Central
Moreover, make sure to unblock MathWorks Service Host from any antivirus, security software, VPNs or proxy servers.
Hope this helps!
