2021-07-27T04:46:21.863+00:00 Yes, I have enabled the long path from Local Computer Policy > Computer Configuration > Administrative Templates > System > Filesystem.
But when I build my UWP application in visual studio 2019 with configuration Release and platform x64, I am getting the below error.LOGGERBASEDEXECTASK : ILC error ILC1304: The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.

2021-07-27T07:18:39.697+00:00 Are you using StorageFile.GetFileFromPathAsync(String) Method? Or FileOpenPicker?

2021-07-28T02:53:50.613+00:00 Could you please try to deploy your app directly to your device, then run the app from the Start menu instead of the Visual Studio to check if your app could get the file correctly?
