I'm using 2019a Matlab version and have just tried installing 2019b together with the toolboxes. I see the following set of errors on the Matlab screen, when I try to launch it. The screenshot is attached.Matlab 2019b error.jpg

Looks like something has gone wrong with your installation. Please contact MathWorks support to resolve this.

The solution was to delete the Matlab shortcut and launch Matlab.exe

I had this same problem with 2018b and now again with 2019b. Last year, Matlab Support solved it with the following solution:
=============================
Thank you for contacting MathWorks Support. The error you are receiving is usually caused by MATLAB having a pathing error. To resolve this error, please run the following commands in MATLAB in order:
restoredefaultpath
savepath
Once done, restart MATLAB and see if the error persists, if it does, please let me know so I can provide further troubleshooting.
=============================
Hope it works for you.
