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

What subscription do you have?

Pro

What platform is your computer?

Darwin 25.3.0 arm64 arm

What issue are you seeing?

The app just flickers from loading to chat. I cant use it at all... I have even deleted the app, downloaded again and installed, the same behaviour every time.

I took a screenshot today a bit before it stopped working, now that I think about it, it may be the root cause:

running codex cli, i got this logs:


⚠ MCP client for `codex_apps` failed to start: MCP startup failed: handshaking with MCP server failed: Send message error Transport
  [rmcp::transport::worker::WorkerTransport<rmcp::transport::streamable_http_client::StreamableHttpClientWorker<codex_rmcp_client::http_client_adapter::StreamableHttpClientAdapter>>] error: unexpected server response: HTTP 401: {
    "error": {
      "message": "Your authentication token has been invalidated. Please try signing in again.",
      "type": "invalid_request_error",
      "code": "token_invalidated",
      "param": null
    },
    "status": 401
  }, when send initialize request

so i just run codex logout and opened chat gpt, logged in again, and finally i got it unstuck, working properly...

I have no idea how i came to this state, but it should be auto resolved if it happens...

Token was explicitly invalidated; logout/login restored operation.
