 | No MCP settings entry | Confirm your desktop version meets the requirement above, then open the installed ReMe detail and its `reme` MCP card; confirm it is enabled and restart. |
 | Hooks settings keep loading or do not show ReMe | Open a local project folder and select the local host before reopening Hooks settings; see below. |
+| Status cannot open after an update, with `No such file or directory` pointing to an old plugin version | Fully quit and reopen Codex, then reopen ReMe status from MCP settings. Closing the card or starting a new conversation does not reload an existing MCP connection. |
 | Blank status card followed by a plugin feature loading error | Check network access to the Codex sandbox page; see below. |
 | Connection healthy, no recording or recall | Review every ReMe Hook; check the auto switches and recent activity. Health does not prove Hook execution. |
 | Turns stay queued | Keep Codex and ReMe running. Check the ReMe model configuration and service logs, and confirm the startup command includes `service.tool_error_on_failure=true`. |

 | Hooks 设置一直加载或没有 ReMe | 先打开本地项目文件夹并选择本机，再重新进入 Hooks 设置；见下方说明。 |

 | 状态卡片空白，随后提示“插件功能未成功加载” | 检查 Codex 沙箱页面的网络访问；见下方说明。 |
 | 连接健康，但没有记录或召回 | 检查全部 ReMe Hook 的信任状态、自动开关及最近活动；连接健康不代表 Hook 已执行。 |
 | 记录一直在队列中 | 保持 Codex 和 ReMe 运行，检查 ReMe 模型配置和服务日志，并确认启动命令包含 `service.tool_error_on_failure=true`。 |
