Found similar resolved bug report from earlier version 1.11.2 but had incomplete information. I'm opening a new one since this affects 1.13.1 and I have a crash report.
I have been getting random crashes but his one actually had this message along with it.
Copied the following from the final line at the time of the crash from the log file:
