Dear all, I have a similar problem, although the crash report is a bit different (see below). The crash can occur at any point in time, even when I'm entering simple comments (without plotting anything). Help is much appreciated!
If MATLAB is crashing, you can contact MathWorks Technical Support and they can help you identify the cause.
