I created my own link to download files from huggingface since the streamlit button is not working. Have a look over at this space, which also shows the problem with the link: Streamlit Download Experiment - a Hugging Face Space by cansik
But this only works for file sizes that do not exceed the url-charachter limit!
Btw. even downgrading does not work. I tried to stick to an old version of streamlit (like sdk_version: 1.21.0) and adding the altair==4.1.0 requirement (as mentioned here).
