Xamarin中File.Delete()在华为Art-AL00X设备抛出‘owner died’异常求助

• 多数Android设备上文件删除操作可正常执行，但在华为Art-AL00X（Android 10.0 - API 29）设备调用File.Delete()时会抛出‘owner died’异常
• 可正常创建文件并写入数据，但无法删除该文件；此问题为首次遇到，谷歌搜索未找到相关解决方案
• 二次测试发现：若先在文件管理器中查看过该文件，则可顺利删除；未查看过的话删除就会抛出异常

string path = "Want Save Path";
byte[] buffer = new uint8_t[73790];
using (BinaryWriter BW = new BinaryWriter(new FileStream(path, FileMode.Create)))
{
    BW.Write(buffer, 0, (int)exer.Size);
    BW.Flush();
    BW.Close();
    Console.WriteLine("USM:Save Image Data Success");
}
