The same thread was able to respond later via CLI (resume + ping), which suggests a Desktop migration/resumption issue rather than a global account problem.

It's not a duplicate, even if the issue seems to be the same.
The other ticket is relying on an API key, and I don't, I use the ChatGPT Pro subscription + the other issue occurs when running codex, I can use Codex, I just lost all the sessions existing before the Codex App or GPT5.4 update.
Were you using a different account when you created these threads originally? The encryption key is based on the account that you used to sign in.
No, I didn't change the account or even the organization or the subscription or something like that. That's why I think it's an issue. I keep working with the same account for months now, and the organization is the same default one for years now, and my account is working. I pay my subscription, so nothing changed on my side beside the update of the Codex App and GPT 5.4.
I have the exact same problem on the Codex App. Connected via chatgpt subscription on enterprise with SSO enabled.
Codex Version 26.305.950 (863)
I just installed Codex, signed in with my account and that's it.
I've also been running into this the past couple of days. I'm running codex via device-auth in a sandbox and occasionally when i send a follow up message I'll run into this -- it's not consistent though but I've had it happen ~3 times today
