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.
