The stack trace sounds similar to this: https://forums.developer.apple.com/forums/thread/748008

AAChartModel/AAChartKit#1538

Are you running with malloc diagnostics or is this in production?

[mcorner]

Also does this happen on xcode 15.2? Smells like an apple bug, but we will see...

@mcorner Disabling Malloc Stack Logging solved the issue for me. Thank you very much for that suggestion!
