Unable to use codex agent in xcode

Whilst using codex, I got an error "The data couldn’t be read because it isn’t in the correct format." I determined that I was no longer signed in. I went through the OAUTH chain opening a web browser and going through the login. However every time I do it, the account still shows "Not signed In" I am on 26.5. I also removed the codex from components and redownloaded it. That made no difference.

Any one else having these issues? Claude is working.

Thanks for the post, do you have any other Xcode install in that computer? Please take a look at this thread https://developer.apple.com/forums/thread/825837

Thanks
