+
+          Another crash was found in the `file_io` fuzzing target that appears to be a duplicate of this issue.
+
+          ### Details
+
+          - **Crash File**: `${{ needs.io_fuzz.outputs.first_crash_name }}`
+          - **Total Crashes**: ${{ needs.io_fuzz.outputs.crash_count }} found in this run

+          - **Timestamp**: $(date -u +"%Y-%m-%d %H:%M:%S UTC")
+
+          ### Artifacts
+
+          Download crash artifacts from: https://github.com/${{ github.repository }}/actions/runs/${{ github.run_id }}
+
+          The fuzzing infrastructure detected this as a likely duplicate based on similar stack traces and error messages.
