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.

Moreover, make sure to unblock MathWorks Service Host from any antivirus, security software, VPNs or proxy servers.

Hope this helps!
