The code was working a day before with no problem but today the following error appears
Error using message/getString
Unable to find message key 'UnknownError' in catalog 'MATLAB:fullfile'.
Error in fullfile>locHandleError (line 141)
excToThrow = MException(msgToThrow.Identifier, msgToThrow.getString);
Error in fullfile (line 93)
locHandleError(exc, varargin);
Error in toolboxdir (line 37)
s = fullfile(tbxprefix, tbxdirname);

Hi Walter, thanks for your patience. I found out where the problem was! Through a power cut or something, I had managed to save 'fullfile.m' into the current folder without I even notice. So MATLAB confused its own fullfile with the one I had saved in the folder. I removed the file so there is no problem any more.

When you see something about being unable to find the message key, then one of two things has happened:
  1. corrupted MATLAB installation; or
  2. you have too many files open already and MATLAB is not able to open a file it would use to create the correct error message.
In practice the second of those is much more likely. Try
fopen('all')
to see the list of open files.

Thank you, Walter for your prompt answer. I tried fopen('all') and I got '[]'. So I uninstalled MATLAB, restarted my PC, installed it again and restarted my PC. Now I can open the files but I receive same errors. Worth to mention that I can even run the codes and get the results but I still have the red lines error with each try.

What do you see if you
ls(fullfile(toolboxdir('matlab'), 'uitools', 'private', 'icon_error_32.png'))

This is what I get:
Error using message/getString Unable to find message key 'UnknownError' in catalog 'MATLAB:fullfile'.
Error in fullfile>locHandleError (line 141) excToThrow = MException(msgToThrow.Identifier, msgToThrow.getString);
Error in fullfile (line 93) locHandleError(exc, varargin);

Does that happen even if the ls() is the first thing you do after restarting MATLAB ?
