XCode 12.1 build error

Hi everyone, I'm new to XCode and openframeworks.

So I have the Xcode 12.1 and using it on my macOS Catalina (version 10.15.6)

So two days ago I started having a problem where my XCode would Build Successfully, but nothing would launch. I checked for breakpoints, cleaned my build, etc. everything I found on forums but nothing happened.

So eventually I uninstalled my XCode and redownloaded OF folder and the same problem persists, which leads me to think it's an issue with my OS (it recently auto-updated upon restarting my macbook).

At this point I'm just at a loss for what to do. Is it a keychain access issue? I'm just not sure why it won't launch my project after a successful build and could really use help. Most of the advice on this forum is for much older versions of XCode.
