I have used XCode for decades as my default C/C++ programming IDE. I write code that I run locally on my Mac, via "Sign to run locally". Typically this has always "just worked". I am now using MacOS 14.7 Sonoma, and I suddenly find I cannot run my code projects because I cannot dynamically load unsigned libraries. "not valid for use in process: library load disallowed by system policy" BUT - it appears that to allow my local MacOS code to bypass this requires I have a bundle identifier to modify entitlements. Which in turn requires a developer account which I don't have. Is this all correct? Is there any way to have code run locally and use dynamic libraries as I've done previously? Any advice is much appreciated.

I want to (continue to) use XCODE to develop for my personal, local use on my Mac as I have been doing for decades. But on my new computer, in every project, I first try going to the code signing options and select either my developer ID or sign to run locally, and then I choose my personal team name (I'm not professional developing at this point - just learning and running locally.) But on Monterey/M1 and the latest XCode, it won't accept my Personal development team - it just repeats the error "signing for xxx requires selecting a development team", even though I selected my Personal Team. I am very desperate to start developing with my new Mac, and any help to get past the code signing problem is greatly appreciated. I just want my projects to compile and run again. I am willing to pay for help.
