已安装的cv2、numpy库无法导入，程序功能失效求助

我是一名借助ChatGPT开发程序的从业者，有基础编程基础，此前用ChatGPT开发了多个运行正常的业务程序。近期未修改任何代码，但cv2、numpy库突然完全无法使用。

我的代码片段如下：

import os
import cv2
import numpy as np
import tkinter as tk
from tkinter import filedialog

代码中的cv2和numpy被下划线标注且无语法高亮，脚本运行也存在问题。

cv2错误信息 #

        }
    },

该代码用于扫描图像自动裁剪程序，现在点击按钮后无实际裁剪效果，仅提示代码执行完成。
