The Codex plugin review erros because it can't execute shell commands due to bwrap permissions. #18
Description
/codex:review to review my local change within claude code section it shows error:
The Codex review was unable to run — it hit a sandbox restriction (bwrap: loopback: Failed RTM_NEWADDR:
Operation not permitted) that prevented it from executing shell commands to inspect the diff.
This is a known limitation when the Codex companion runs in a restricted sandbox. You can instead use the
MCP-based Codex review we did earlier (which worked successfully), or run the review manually with codex review
from your terminal.

This appears to be a bubblewrap issue with the latest version of Codex. Can you try to follow the Linux steps here?
