Debugging a macOS IPS dump

I have a macOS application built via command line (xcodebuild) using Xcode 16.1. Developed on ARM but end user is on Intel (same macOS 15.1).

App crashed and they sent me a .IPS dump.

From what MacGPT tells me:

Reading an IPS (Incident Processing System) file from a macOS crash report in Xcode isn’t as straightforward as with iOS device logs.

I can open the dump using Console. I see the IPS dump is partially symbolicated.

Line in the dump says: Meteorologist 0x103e0348f 0x103d88000 + 504975

Referencing this article: Adding identifiable symbol names to a crash report | Apple Developer Documentation

I run this command and see the same UUID for x86_64 as in the dump.

dwarfdump --uuid /Users/ed/meteorologist/trunk/Build/Meteorologist.xcarchive/dSYMs/Meteorologist.app.dSYM/Contents/Resources/DWARF/Meteorologist

I run this command:

atos -arch x86_64 -o /Users/ed/meteorologist/trunk/Build/Meteorologist.xcarchive/dSYMs/Meteorologist.app.dSYM/Contents/Resources/DWARF/Meteorologist -l 0x103d88000 0x103e0348f

And it says: fg: no current job

Suggestions for what I’m missing?
