This is a common crash occurring for users in 4.16. It is spread out among around 60 different CrashGroups in CrashReporter, because every case has a slightly different callstack.
This appears to have been experienced by QA during the 4.8 release ([Link Removed] - Landscape garbage collection crash occurred after Force Deleting Map asset) but it was later unable to be reproduced.
Additional user information is not currently available.
