Since updating to 0.30 Codex CLI on Windows i get hit by timeout and bad requests

What version of Codex is running?

0.30-0

Which model were you using?

Gpt5 (on high) / Pro subscription

What platform is your computer?

Microsoft Windows NT 10.0.26100.0 x64

What steps can reproduce the bug?

Work on a semi large project (2-3 LOC)

Ask Codex for a feature that requires complex work and takes a long time, reading several files

After a while i get hit by:

⚠️ stream error: stream disconnected before completion: Transport error: error decoding response body; retrying 1/5 in 201ms…

⚠️ stream error: stream disconnected before completion: Transport error: error decoding response body; retrying 2/5 in 364ms…

⚠️ stream error: unexpected status 400 Bad Request: {
"error": {
"message": "The encrypted content for item rs_68bbc51c113881a39f1d4c1c8d03219301d63254c1f2715a could not be verified.",
"type": "invalid_request_error",
"param": null,
"code": null

.. Goes on with bad request until i restart it

This has happened 5 times now. I restart codex and it helps a bit, but returns. I have used Codex CLI a lot the last two weeks, and all have been fine. This is the first time i see this error

What is the expected behavior?

No errors and timeouts

What do you see instead?

Errors and timeouts
