Regardless of the account or API I use, and regardless of the mode, I get the error message: "Invalid prompt: your prompt was flagged as potentially violating our usage policy. Please try again with a different prompt: https://platform.openai.com/docs/guides/reasoning#advice-on-prompting". Codex simply doesn't work on my computer.

What steps can reproduce the bug?

I'm not entirely sure. After automatically installing CodeX, it only worked the first time, and then started acting like this the next day. I've tried uninstalling and reinstalling it. Changing accounts or APIs doesn't work either.

What is the expected behavior?

Normal operation
