Hi all,
I previously thought this might have been caused by something in my code, but I’ve tried commenting the whole lot out and still it happens.
I have been experiencing this crash ever since version 4.8.1 as far as I can recall, and I’ve tried many things, including deleting the Intermediate and Saved directories inside my projects, clearing the Derived Data Cache and removing blueprint assets.
It’s an annoyance more than anything, as the compile seems to work. After I restart the engine after the crash my code runs perfectly. The stack trace is below, which has come out pretty much identical for every crash (and there have been a lot!)
Hopefully someone can clarify if this is a bug or make any suggestions as to something I might be doing wrong.
