MATLAB is selecting SOFTWARE OPENGL rendering.
License checkout failed.
License Manager Error -9
Your username does not match the username in the license file. 
To run on this computer, you must run the Activation client to reactivate your license.

The license path including /root/.matlab/R2019b_licenses could be a problem: they are obviously on Linux and they would not be running the software as "root" . You might need to adjust the LM_LICENSE_FILE environment variable, or you might need to delete the one in /root so that the software continues on to check the other locations.
