I had just finished adding some ambient music to the level and clicked play to open Creative Edit and consistently every time my UEFN will crash while opening Creative Edit, I tested 4 times.
Hi @DolphinDom, in addition to what @Flak mentioned, when you crashed, by any chance, did the Crash Reporter dialog show up and did you manage to report the crash using it that way? I had trouble trying to identify a crash that came from you and I’m wondering if something else went wrong in the Crash Reporter itself.
EDIT: Never mind, I found it. Thanks for the report!
