I was invited to test the new Codex for Windows app. After installing it, I started to receive {"detail":"Bad Request"} errors on each session, generally within 10 minutes into execution. The errors have been occurring in both the new Codex for Windows app and the Codex VS Code extension. I thought it might be a conflict between the two, so I uninstalled both as well as VS Code. I deleted every file I could find related to Codex or VS Code from my pc. I reinstalled VS Code and the Codex extension. The error has not gone away.
