Deadline on Apple M1 is unstable

We’ve not had any luck reliably re-creating this issue to root-cause the issue; it is as intermittent for you folks as it is for us. We’ve got an engineering issue rolling, but we can’t share any details about when it would be resolved, or when a release with a fix would happen due to Amazon policy.

QT seems to be the common denominator in the spinlogs we’ve gotten in this thread and in Worker randomly crashing on MacOS M2 Ultra. We only use QT to create the UI. Which means running the Worker with -nogui should resolve the issue, but that’s not what we’ve been seeing.

If possible, could we get a spinlog from a crash when running the Worker with the -nogui flag? It could be there’s two causes of a hang and crash, and the second only gets to show up with QT removed from the equation.

Thanks!
