This is an infrequent Mac crash that has been affecting users since at least 4.15. Users have not provided any descriptions of their actions when the crash occurred.
The callstack is similar to the one reported in [Link Removed], but that was fixed in 4.17 and that specific callstack has stopped occurring, while this one still continues.
