MATLAB 2025b not launching

I recently did a firmware update on my linux machine and after that I am not able to launch MATLAB 2025b.

This is the error I get:

MathWorks Licensing Error 9

A licensing error occurred while trying to use MATLAB.

The host ID '843a5b57c8e7' in the license file does not match your computer's host ID: c0a810c2b168.

To resolve this issue, reactivate your license.

Dear @Srikar

To resolve this, verify the Host ID (MAC address) of the machine, then reactivate MATLAB. If your machine has a variable Host ID, configure your system to have a static Host ID, and then reactivate MATLAB.

Hope this helps!
