SwiftUI/AttributeGraph crash

I'm getting this segfault stack trace from TestFlight. Any idea about how I should approach it?

High up in the trace there's some ZStack layout stuff. Maybe just trying to simplify my view hierarchy?

(I wonder if this would be more stable if AttributeGraph wasn't written in C++)

Hi Audulus,

There isn't much to go off of from this snippet of the crash report. Could you please attach the crashing project and related symbolicated crash logs to a new submission in Feedback Assistant? Once submitted, please respond here with the Feedback ID so we can determine the most appropriate next step.

Cheers,

Paris
