We are still not aware of such a crash. I tried to reproduce it locally but with no success. Could you please provide some further information on the initial set-up, steps to reproduce and the whole stack trace of the exception? Actually, the best way to approach such a problem is to send us a sample project which demonstrates the issue and a video with exact steps to reproduce.
In the meantime, could you please check if the described behaviour is reproducible in our online demo: Telerik Editor Demo
Once we are able to reproduce the issue, we will do our best to assist. I am waiting for your reply.
