Empty directories of files missing

[navimakarov]

Empty directories, even though, files exist. I have all permissions in Manifest and android:requestLegacyExternalStorage="true"
I ask for permission request additionally in runtime. What is the problem?

MaterialFilePicker()
.withActivity(this)
.withCloseMenu(false)
.withHiddenFiles(true)
.withFilterDirectories(true)
.withTitle("Preview File")
.withRequestCode(FILE_PICKER_REQUEST_CODE)
.start()
