I have installed Matlab version 9.5.0.944444 (R2018b)
Now the matlab HELP service stopped to work.
What might be the reason for this failure?
Regards

Make sure that you are not overriding any functions called by help.m with mfiles of your own. For example, if you have your own mfile called strip.m, it may shadow the strip() method of Matlab's string class, which help.m does invoke.
One way to trap such problems is to activate the debugger with,
>> dbstop if caught error
and then test your call to help() again.

Another good first troubleshooting step would be to
>>restoredefaultpath
and to disable any startup.m files you have.
