What version of the Codex App are you using (From “About Codex” dialog)?
Current
What subscription do you have?
PLUS
What platform is your computer?
HP Windows 10/11
What issue are you seeing?
windows sandbox: helper_unknown_error: apply deny-read ACLs
File tools fail before reading any workspace file; restarting the task/app did not resolve it.
What steps can reproduce the bug?
Everytime I try to add slides to my slide deck, it says: "The task is blocked by Codex’s Windows file-sandbox bug, so I can’t access or export the deck despite having the slide content. Please stop retrying this task. "
What is the expected behavior?
I would like to continue to build my slide deck using PDF and outside resources.
