What issue are you seeing?

I directly use /review command to review uncommit code, but failed and told me
" I could not inspect the repository state because every shell command failed in the current sandbox (bwrap: loopback: Failed RTM_NEWADDR: Operation not permitted), so I found no actionable issues from the available context."
Then I give it full access via /approvals command and run /review again. This time codex updates plan first using update_plan tool and then still failed:
“ I could not inspect the staged/unstaged/untracked changes because every attempt to read the
working tree failed in this environment with bwrap: loopback: Failed RTM_NEWADDR: Operation not
permitted. Since the patch could not be validated, it should not be considered correct based on
this review.”

The full procedure like following:

> Code review started: current changes <<

› Review the current code changes (staged, unstaged, and untracked files) and provide prioritized
findings.

I could not inspect the repository state because every shell command failed in the current
sandbox (bwrap: loopback: Failed RTM_NEWADDR: Operation not permitted), so I found no actionable
issues from the available context.

<< Code review finished >>

• Updated Plan
└ □ Inspect repository status and diffs
□ Analyze changes for actionable bugs
□ Produce prioritized review findings JSON

• Updated Plan
└ Shell commands are blocked by the sandbox (bwrap: loopback: Failed RTM_NEWADDR: Operation not
permitted), so I couldn't inspect the working tree or diffs. Proceeding with a transparent,
no-findings result rather than inventing issues.
