Same issue here on Windows, latest version. It gets stuck on the loading screen and never opens, and CPU usage shoots up. I didn’t change anything on my side, just started happening today.

I also encountered the same problem and finally solved it with a temporary solution.
You can delete the auth.json file in the .codex folder, then log in to codex again. It will freeze for a while, but wait a moment and it will work normally.
