Note to self: this stack trace is very obscured. But the stack trace looks similar to #1365

Hi @danhalliday thanks again for reporting all of these crashes and stack traces.
We made more crash fixes since version 5.1.3. Please update to Release 5.1.6 or later, and let us know if the crashes are resolved, or what crashes still remain.

@nan-li Thank you for your help. I am still waiting for my release containing 5.1.6 to roll to 100% of my user base so I’ll know more in a week or so. But right now I can say I’m still seeing at least one issue. I have two crashes reported from my new release, here are the traces.
