File.Delete() throw "owner died" in Xamarin

Question

Generally, file deletion can be performed correctly on most Android phones However, when I run this line of code on "Huawei art-al00x (Android 10.0 - API 29)", the operation throws an exception "owner died"

I can create files and write data, but I can't delete files

I've never been in this situation before

After Google searched, there is still no result

After the second test, I found that if I checked the file in the file manager, I could delete it smoothly, while if I didn't check the file, it would throw an exception

The Code:

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");
}
