This is a somewhat common crash in 4.17.1. This same callstack appeared a few times during 4.11, but then has not been seen until recently. Users have not provided any descriptions of their actions when the crash occurred.
The callstack shares some similarities to
UE-38225, which surfaced during 4.12 and 4.13, but did not appear to occur into 4.14.
repro steps currently unknown
