Hi Ivan de Souza,
I looked up your crash data and found this bug has been fixed in UE4.14. (UE-34370). I suggest downloading UE4.14 and opening a COPY of your project in UE4.14, not overwriting the original, and only after making a back up of your project somewhere outside of the Unreal Projects folder.
Let me know if this does not resolve your issue.
Thanks,
.
