Game crashes when going to CAS from within the game

If I click on a Sim and click go to CAS, very often the game locks up and I have to restart. Better Exceptions come up with an extensive explanation as below.

Is there something I can do to prevent this? It has been happening for some weeks, so not due to your latest patches.

Thanks.
