Thanks, but it is not a good solution. Org cannot rely on internal
variables inside python.el (python-shell--first-prompt-received is an
internal variable). Internal variables are a subject of change without
notice.
May you instead try the attached alternative patch?

Subject: [PATCH v2] ob-python: Fix Emacs bug#50514 when Python loads slowly
* lisp/ob-python.el (org-babel-python-initiate-session-by-key): Do not
rely on 10ms delay to initialize Python. Wait until python process is
initialized using `org-babel-comint-wait-for-output'.
