Is the error initializing Java Preferences Failed in matlabrc important?

I'm a student and tried downloading a pirated version of matlab, which obviously didn't work. I then removed that program from my computer, and downloaded the trial version of matlab. However, when I load up matlab, the above error appears.

Wondering what will be affected by it, and how can I get rid of that error.

Hi JJ,

It seems like your MATLAB installation is corrupted, try performing a clean installation of MATLAB as per this MATLAB Answers post- https://www.mathworks.com/matlabcentral/answers/131519-how-do-i-perform-a-clean-installation-of-matlab
