This is a semi-common crash that has occurred since at least 4.17.1. The callstack is nearly identical to [Link Removed], which was fixed in 4.18.0, however the error message and source context are different. Users have not provided any descriptions of their actions when the crash occurred.
Edit, this may actually be a continuation of [Link Removed], but I've gone ahead and closed that one out.
