Matlab crashes when using stateflow library block.

When working in my stateflow model, matlab crashes very often at 'random' times giving me this error:

A technical support engineer might contact you with further information.

Thank you for your help.

What could be the issue here? It is a Simulink model with custom library blocks in it, which are stateflow charts. MATLAB crashes when editing the code in the stateflow chart, so not during simulation.

Kind regards, Brecht
