Hello ZACRUDIN,

In order to attempt to reproduce your crash, I will require a bit more information:

  • Could you attempt to reproduce the crash, and ensure that you send the Crash Report when the window appears?
  • Could you post your logs?

One thing you could try is to go into your project folder and delete the Intermediate and Saved folders, and then see if the crash still occurs.
