Sep 1st 2026. I was using Codex Plus in Xcode 26.6 then I upgraded to Codex Pro and everything broke. Exact same issues as everyone else in this thread. I've tried completely uninstalling xcode and restarting/reinstalling, purging cache, deleting and manually clearing folders where the Intelligences are installed. Tried linking it via chatgpt login, openapi key, and configuration file. The openapi and configuration file options did show as signed in, but it still failed to authenticate when I tried to actually use the chat. FB24616047
