Hello,
After looking into your crash, I’m seeing something that’s slightly similar in callstack that has been resolved in 4.14.
Would you mind opening a copy of your project in 4.14 to see if the same crash occurs?
If it is a certain map causing the issue, it might be worth rolling back to an older version of the file as well to see if there was a particular change that could have caused this crash to occur.
Also, I’d recommend checking your log in your project’s Saved->Logs folder. It looks like there are some animation errors that could use resolution. Not saying that this is the cause of the crash, but it’s worth a shot.
Let me know if any of that helps!
