Env: macOS 13.6.4, Xcode 15.2, MBP M1 Pro
I am building/debugging a fairly simple C++ app which is meant to show some basic .dylib functionality. I received the Xcode project/source/libraries, which compile just fine, but when I attempt to run the "debug" version, it crashes before it gets to main():

I am not that familiar with Xcode debugging - where can I look to find why findAndRunAllInitializers() is failing?
