In certain cases I get nothing from the continued_fraction function

Try doing
continued_fraction(a,bits=100)
This solves the problem for me. I believe the issue is that with the
default precision it doesn't know if the number is less than or greater
than 2, so it can't determine the first quotient. the number 100 was
fairly arbitrary, the default I think is 52.

In version 4.5.2 the output was
