This is a common Mac crash occurring in the 4.16.1 release. I have not found any evidence of it occurring on Windows.
The callstack closely matches [Link Removed], which was briefly experienced by QA in 4.16.0, but then could not be reproduced later.
Users have not provided any descriptions, so additional information is currently unavailable.
