Hi,
I recently installed Matlab R2019b and my Matlab help documentation just appears as a black screen.
I had no such issues in the previous version I had installed (R2019a)
Any suggestions how to get my help documentation window ??
Attaching a screenshot of the issue.
I also get the following error message in my command terminal, does this have anything to do with my issue??

Have you tried installing libselinux and restarting matlab?

yeah, that did not help. I just learnt to live with it and use the online matlab documentation for functions

@LOKENDRA
This was a fix for the arch linux OS, not Windows

Unfortunately, after my latest Manjaro system update, the problem has resurfaced.
The previous fix of usinh libselinux and libsepol does not help anymore.
I guess I am missing a few more packages

After my most recent Majaro system update on 29th Aug 2020, I faced the same issue again.
This time , just installing the libsepol and libselinux packages did not help
The error that was now thrown to me was:
/usr/local/MATLAB/R2019b/bin/glnxa64/jcef_helper: symbol lookup error: /usr/lib/libpango-1.0.so.0: undefined symbol: g_ptr_array_copy
these are the commands I used:
mkdir $Matlab_root/cefclient/sys/os/glnxa64/0_excluded
mv $Matlab_root/cefclient/sys/os/glnxa64/libg* $Matlab_root/cefclient/sys/os/glnxa64/0_excluded
I can now view my Documentation window and the Live scripts
