Hi,
The following steps will place the point at the beginning of the line
"def foo():", not the line "def bar():".
1. emacs -Q
2. Load the following Python file using M-x find-file
#+begin_src python
def foo():
def bar():
pass
def baz():
pass
#+end_src
3. M-: (forward-line 2)
4. M-: (python-nav-beginning-of-defun)
python-nav-end-of-defun has a similar problem.
Best Regards,

Hello,
I'm afraid this is a bug in my patch to fix #56105. It initialized
`min-indentation' using `current-indentation' of the current line.
However, it was not adequate for an empty line as
`current-indentation' of an empty line is zero.
Attached is a patch to fix this issue.
Best Regards,
