```运行项目Demo ：选择主题样式三 -> 选择使用自定义相机 ->开始长按录制 -> 黑屏
```

Start by running the demo with version 3.11.1 on HarmonyOS 3.0 and a Honor 80, then follow the reported path: theme style three, custom camera, and long-press video recording. Trace the custom-camera recording entry point and verify that recording no longer produces a black screen.
