What version of the Codex App are you using (From “About Codex” dialog)?

the latest

What subscription do you have?

Plus

What platform is your computer?

Windows 11 Pro

What issue are you seeing?

I completely removed the ChatGPT/Codex app, including the registry entries and local files, because I noticed that some deleted chats were still showing up in the Windows app.

After reinstalling the app, I'm now stuck during the Codex Windows setup. I get the following error:

“Setup didn’t finish. Setup could not complete.”

My config.toml contains:

sandbox = "unelevated"

I tried renaming config.toml to force the app to create a new one. I also tried the same with auth.json, but neither worked.

I also tried reinstalling and repairing the app, with no success.

Any ideas on how to fix this?

What steps can reproduce the bug?
