Can not read or write external storage even though permissions granted

Permissions are granted but can not read and write

boolean write = checkSelfPermission(android.Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED;
boolean read = checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED;

Log.e(TAG, "aaaa WRITE=" + write + ", READ=" + read);
File dir = Environment.getExternalStorageDirectory();
Log.e(TAG, "aaaa DIR=" + dir);
Log.e(TAG, "aaaa canRead=" + dir.canRead() + " canWrite=" + dir.canWrite() + " canExecute=" + dir.canExecute());

prints:

2021-06-12 12:30:07.256 3196-3196/ aaaa WRITE=true, READ=true
2021-06-12 12:30:07.257 3196-3196/ aaaa DIR=/storage/emulated/0
2021-06-12 12:30:07.260 3196-3196/ aaaa canRead=false canWrite=false canExecute=true
