未修改代码突发异常：Next.js应用布局错乱、组件消失求助

我的Next.js应用此前运行完全正常，但今早执行npm run dev启动项目时，未修改任何代码却出现严重问题：所有组件布局混乱，原本左侧是图片和文本、右侧是两个带文本的滚动视频的中间组件完全失效，部分组件从屏幕上消失，同时CSS样式也出现错乱。多次撤销操作确认没有误删代码，但问题依然存在。

• 修复代码拼写错误：代码里存在明显的组件引用错误，直接导致渲染失败和布局错乱：
  • 将<SwapComs />改为<SwapComponents />（对应导入的SwapComponents）
  • 将<PriceScript />改为<PriceUpdater />（对应导入的PriceUpdater）
  • 将Image组件的src={pic.src}改为src={coin.src}（pic未定义，已导入coin但未使用）
• 回滚依赖版本：如果自动执行了npm install，可能导致依赖包（如Next.js、Tailwind CSS、onchainkit）版本更新引发兼容性问题。恢复之前的package-lock.json或yarn.lock文件，再执行npm ci安装固定版本依赖。
• 清除Next.js缓存：删除项目根目录下的.next文件夹，重新启动项目：

  rm -rf .next && npm run dev
  

• 检查Tailwind配置：确认tailwind.config.js中的content数组包含所有组件文件路径，避免样式无法正确生成。
• 强制刷新浏览器缓存：使用Ctrl+Shift+R（Windows/Linux）或Cmd+Shift+R（Mac）强制刷新页面，清除旧的静态资源缓存。
