encoding has some issue with Transformers == 4.48.1

TypeError: cannot unpack non-iterable NoneType object

when i call .encode(). i did some debugging, it happens deep down when the __call__ of nn.Module is called, with _impl_call_ etc, and that's where i gave up figuring out more.

on 4.47.1 it works well.
i used torch 2.4.1 as well as 2.5 but seems like Transformer version is the core issue.

I experience this as well with 4.48.1

also breaks with torch 2.6
