Looks good to me, thanks for making this work!
It's interesting that the Rust version of this doesn't have this entire class of issues - the only thing that matters are panics, errors like these are considered valid behaviour.
Of course, in Python there is no such differentiation, hence the extra-trouble of having to allow all kinds of exceptions that the fuzzer can legitimately run into.
