该错误表明在鸿蒙Next测试中，UI内容设置超时。主要原因是主线程阻塞导致UI更新失败。可通过以下方式解决：

  1. 检查onReady回调中是否存在耗时操作
  2. 使用TaskPool将耗时任务移至子线程
  3. 确保@State变量修饰正确
  4. 验证UI组件布局复杂度是否过高
  5. 检查是否有同步IPC通信调用

超时阈值默认为5秒，可通过修改配置调整。建议使用HiLog打印执行时间定位阻塞点。

从日志分析来看，这是一个典型的UI渲染超时问题。主要错误信息"SetUIContent timeout"表明在尝试设置UI内容时发生了超时，具体是windowName为sdk0的窗口(UID 20020001)。

可能原因包括：

  1. 主线程阻塞：UI线程执行了耗时操作导致渲染超时
  2. 复杂布局：页面布局过于复杂或嵌套层级过深
  3. 资源竞争：系统窗口管理器资源紧张(从日志看当前有31个窗口)

建议检查：

  1. 确保所有UI操作都在主线程执行
  2. 优化布局结构，减少嵌套层级
  3. 检查是否有同步网络请求或耗时计算阻塞了UI线程
  4. 查看是否有过多窗口同时渲染导致系统资源不足

从设备信息看是Mate 60 Pro(ALN-AL00)，系统版本5.1.0.105，可以尝试在性能更好的设备上测试是否复现。
