@funwithstuff, thanks to the crash reports you provided, we were able to identify a likely cause.
The logs in all of your crash reports show the screens going to sleep and waking up. On some systems (including yours), macOS apparently reconfigures the displays upon waking up. This leads to crashes that look very similar to this other bug report.
We already have a fix for the other bug report scheduled for the upcoming Vuo 2.4.1 release. Although we haven’t actually been able to reproduce your crashes to confirm, we think it’s likely that they’ll also be fixed.
Great — thanks for tracking that down. My Mac does change monitor setup quite a bit (laptop into TB dock with monitor connected) so a bug related to that would cause issues. Awesome!
