Oh I guess MANAGE_EXTERNAL_STORAGE was introduced in android 11 and higher.

Can you explain how it doesn't set, does the file picker not show up, or when selecting one it doesn't display it or it says the path changed but hitting next reverts back to app path? I want to know where the issue appears.

Yes. I tried to fix It using adb. But manage External storage doesn't exist in Android 10.

When i install the app It propmts optionally to change preset folder, so i click on that opción then Select fólder, but nothing happen all the file were not appear in the screen. Then i go to setting AND realize that preset fólder wasnt changed.

I repeat again changing default fólder now from setting section, it open document_UI picker again i Select folder , It Accept, but then the app' main screen hasnt changed, It Is still without nothing. (Android 10)

Sorry I was working and didn't have much time to look into it, apparently it is just a failing permission check issue, when you select a folder, phone should prompt to allow managerExternalStorage, and it fails since it is not isGranted so it doesn't return the path selected at all. I will add check to return if older than android 11 to the next release, I will warn that only tend to release after a few things get added to an update, so it can take a while.

If you need a fix now, best I can do is compile a single android apk and share it here, you just may get a versioning issue with the next release as that might require deleting the app I send here with the next official release as they will probably have the save version number.

I did some more testing and yes manageExternalStorage is bypassed, but android will still will not let you read and write files as it wants permissions to be handled using androids SAF (Storage Access Framework) which works completely differently to how I implemented app using absolute paths to have cross-platform compatibility. For this exact problem, I had to start a project to create my own library to use SAF on android and FileSystemEntity for everything else, as nothing like this exists.

Here is the library if you are interested: SSM

I will be honest it is very boring to test every possible edge case so that is why it isn't getting worked on much, plus this is all hobby projects so it doesn't have priority when I am already busy with work most of the time.
