What version of the Codex App are you using (From “About Codex” dialog)?
Versão 26.818.32112
What subscription do you have?
PLUS
What platform is your computer?
Windows 11 X64
What issue are you seeing?
The latest Codex desktop update is causing an error in the sandbox, this message appears. I tested a read-only operation (Get-Location and git status) and the sandbox failed before running the command, with the same error: helper_unknown_error: setup refresh had errors. So, the problem is still with the local Codex environment startup, not the project.
What steps can reproduce the bug?
when I request a code change that he has to access the folders of the research project
What is the expected behavior?
