Error Message

After seeing an update prompt in the top-left corner of the Codex desktop app, I clicked update and restarted. Afterward, the long conversations I had been working on would no longer load. I have several ongoing conversations with rollout files around 150M-170M, and I can't open any of them. When I try to open them, the error message shown in the image above appears, and clicking the retry button or restarting the app has no effect. After the update, my shorter conversations can still be opened as usual, but these long conversations repeatedly show this error no matter what I do. Please resolve this as soon as possible!!

Before this update, my conversations were working completely normally.
