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 hope this will work, if not try contact mathwork support click here
