Updates / potential hints

Placing the CSV file at the Music location instead of Download, the import works without problems. For me it looks like the storage API changes are not aligned with the app (see: Access documents and other files from shared storage)

On Android 11 (API level 30) and higher, you cannot use the ACTION_OPEN_DOCUMENT intent action to request that the user select individual files from the following directories

Since API level 29 is used as app target, the following could fix the issue:

Scoped storage enforcement Apps that run on Android 11 but target Android 10 (API level 29) can still request the requestLegacyExternalStorage attribute. This flag allows apps to temporarily opt out of the changes associated with scoped storage, such as granting access to different directories and different types of media files. After you update your app to target Android 11, the system ignores the requestLegacyExternalStorage flag.
