Won't Fix. Caused by a stale pointer in GC. This type of a crash and the associated callstack usually means there's a problem with higher level code (game) referencing deleted actors. Most likely game specific error.
This is a common crash affecting users in 4.16. Over 100 users have been affected, although they have not provided additional information.
