   Thank you @phofl for contributing!
   
   As I mentioned in the issue comments, there is already a PR for a duplicated GitHub issue: https://github.com/apache/arrow/pull/34289
   
   As you can see in the comments of the duplicated PR issue https://github.com/apache/arrow/issues/33727#issuecomment-1387323624, the failure happens because `pa.DictionaryArray.from_array` doesn't accept chunked arrays. In this case, the ChunkedArray will always have only one chunk and so a better way of solving the issue is to return an array in case of single chunked data when calling `_handle_arrow_array_protocol` (`__arrow_array__`).
