Why does my MatLab documentation seem to be missing after a (very) recent license renewal?

Before the renewal and upgrade, MatLab's help was working very well. Now, whenever I search Help for a word, MatLab's Help feature responds, "An error occurred searching the documentation.".

How can I fix MatLab's Help feature?

I did fix it. This was caused by an incorrect file, that have been left behind in my %TEMP% directory by the previous MATLAB release. It has been fixed when I cleaned-up old data (deleted everything which is inside my %TEMP% Directory). You Can at first uninstall the old Version. Than you can use the MATLAB "tempdir" function to find the location of your %TEMP% directory.

After upgrading to 2019a (Mac), I got a similar problem (Help/Documetation - "The server at localhost can't be found"). I tried "tempdir" function. But there are approx. 90 files in that folder. Which one shall I delete?
