Code Generation Segmentation Fault

I am trying to generate an executable from my Matlab Code. I have done this in the past with this same codebase and it worked fine. I am now getting segmentation fault errors when I run the executable in Terminal:

mshafer@dev567 detector % ./detectstreaming

zsh: segmentation fault ./detectstreaming

Coder says the code generation was successful (see below-bottom), but I am getting a lot of messages like Requested but did not find extension point with identifier Xcode.IDEKit in the build logs (see below and attached). The full listing of build messages is in the attached report .mat files in the ReportInfo.BuildLogs.Text. I am running R2022a, I'm on macOS 12.4, and I have XCode 13.4 installed. Running xcode-select -p in terminal produces /Applications/Xcode.app/Contents/Developer which is the currect directory for XCode. When I convert my Coder project to a script I get the following, which is important if you want to know my coder config settings:

% DETECTSTREAMING_SCRIPT   Generate executable detectstreaming from
%  detectstreaming.
% 
% Script generated from project 'detectstreaming.prj' on 14-Jun-2022.
% 
% See also CODER, CODER.CONFIG, CODER.TYPEOF, CODEGEN.
%% Create configuration object of class 'coder.CodeConfig'.
cfg = coder.config('exe','ecoder',false);
cfg.TargetLang = 'C++';
cfg.GenerateExampleMain = 'GenerateCodeAndCompile';
cfg.GenerateReport = true;
cfg.MaxIdLength = 1024;
cfg.ReportPotentialDifferences = false;
%% Invoke MATLAB Coder.
cd('/Users/mshafer/Desktop/PLAYGROUND/CODE_TOEPLITZ/uavrt_detection/detector');
codegen -config cfg detectstreaming

Please help. This was working previously, but I don't know what changed to cause the current problem.

I figured out the problem. In my code, I has a relative path that pointed to a configuration file my code needed that used to be in a subdirectory. That folder was recently moved, but replacing the folder back in the directory where the executable was generated and run from solved the segmentation fault issue. I still don't know why I was getting all those XCode messages, but they seem to be unrelated to the 'Segmentation Fault' error.
