Please try stopping the MATLAB Web App Server and manually removing/renaming the USR directory, which sits in the same folder as the app or log folder. For example, the default directory for Windows is "C:\ProgramData\MathWorks\webapps\R20xxx\USR" and for Linux is "/usr/local/MATLAB/MATLAB_Web_App_Server/R20xxx/USR" 

After the directory is removed/renamed, try starting again. If you are still experiencing issues, you can run the following commands from the scripts folder to uninstall MATLAB Web App Server and then reinstall it:

webapps-uninstall

webapps-setup
