It is required to add a check for an existing file, if it was created by your app locally and is not registered with resolver. (Got NPE cursor is null)

fun getFileName(context: Context, uri: Uri): String {
    uri.path?.let {
        val file = File(it)
        if (file.exists()) return file.name
    }

    val resolver = context.contentResolver
    val cursor = resolver.query(...)

Perhaps the code that I posted can be used to resolve the issues here and get it working. I use my code to compress any files on Android 10. https://github.com/zetbaitsu/Compressor/issues/163#issuecomment-755061994
