bug描述
同样的脚本 有时候运行时可以找元素 用例正常 但是有时候又找不到元素 可以确定脚本定位的元素没问题 在airtest ide上面有试过。

**复现步骤：**
有留意过一个现象 执行成功的时候 设备上进入小程序页面会浮现poco的提示语 执行失败的时候没有出现poco

**python 版本:** `python3.9`

**操作系统:** `mact`

**手机设备信息:**
- 手机型号:华为 Mate10
- Android系统版本号: Android10
- (别的信息)

**其他相关信息补充**
- AirtestIDE版本号：1.2.9
- 尝试卸载重新安装pocoSevices后一段时间又正常可以了，但是运行一段时间后又不行了

**截屏**
强烈建议带上截图，包括IDE本身的截图和后面的黑窗口的报错信息的截图（尽量完整）。
