Javascript '；找不到字体系列标记'；在Android上使用Chrome浏览器上传时

我有一个上传照片的javascript应用程序。在我的Chrome浏览器中进行本地开发时，上载工作正常。但是，当我在安卓手机（或安卓记事本）上运行应用程序时，它会忽略我第一次选择照片时，只在第二次选择照片时起作用。在选择现有照片或拍摄照片时（第一次什么都没有发生，第二次按原样上传）会出现这种情况。我试着用Chrome远程设备的usb连接来调试它，但突然“bug”消失了（照片在第一选择中上传）

我还尝试了另一件事：我选择了

chrome://user-actions

在另一个chrome选项卡中。然而，一旦我这样做了，bug又消失了，它就正常工作了，所以我无法调试

在Firefox和Safari上，照片的上传工作正常

我安装了Android Studio，现在可以通过usb连接手机，并在Android Studio的Logcat窗口中获取有用的日志。当错误发生时，我会得到以下日志，这些日志看起来像是罪魁祸首：

E/ResourcesCompat: Failed to find font-family tag

我找到的唯一一个指针是，对于所有故障，

查找字体系列标记失败

位于

读取cpu频率统计失败

之前

有什么线索吗
