What caused it? Yesterday As soon as I started MATLAB, I saw a bunch of Java errors in the command window but when I restarted, it didn't show them. The same thing happened later in the day.

The error message you are encountering indicates that the startup preferences for MATLAB are invalid or corrupt.

I suggest you try to to recreate the preferences currently in place on your system using the following article on the MATLAB Answers forum: https://www.mathworks.com/matlabcentral/answers/99625

Try following the steps outlined there, and after doing so launch MATLAB again to check if it resolves the error.
