I also have the same problem. And my operating system and matlab version are the same as yours. I also found that when I ran matlab as non-root user, the help browser would only show blank page. when I ran matlab as root, All the problems were solved.

Thank you for your solution!

Try below steps:

1. Refresh the file system caches using the following commands:

>> restoredefaultpath
>> rehash toolboxcache

2. Run the following command to rebuild Simulink and Library menus and toolbars:

>> sl_refresh_customizations

3. Close all the instance of MATLAB and then restart.

I tried this suggestion in Matlab command window as root, then restarted. It did not work for me.
