can you share the binder link that led to this issue? different repositories launch different environments, so I need the link to understand where the error comes from.

but based on the traceback, it seems like this is due to an incompatibility between nbconvert and jinja2

This is the one

I upgraded from Python 3.9 -> 3.10 and it now works. it was an nbconvert imcompatibility.
