Hi,

There is an incompatability between the versions of python3-markdown2 and
python3-pygments in bookworm currently.

There is a Github issue here explaining the issue:
https://github.com/trentm/python-markdown2/issues/438

And the fix merged here:
https://github.com/trentm/python-markdown2/pull/437

Essentially Pygments 2.12 (bookworm is currently on 2.14) changed a function
signature that python3-markdown2 uses when parsing fenced code blocks, i.e.:

```
foo
```

I think the bugfix was released in python3-markdown2 2.4.3, bookworm is
currently on 2.4.1

Thanks,
Peter
