This is another Tutorial crash that shares a similar callstack with [Link Removed] and [Link Removed], but those specific repro steps have been fixed while this one is still occurring in 4.16.2. One user mentioned crashing while loading the Landscape tutorial, but I have so far been unable to find the repro.
repro steps currently unknown
