@gaon in response to your request on where I got my ideas on the original issur of women learning, I looked up the topic.
I realized that I synthesised two sources:
Here are all the sources that forbid women’s learning :
The Rambam writes in hilchos tt Sof perek aleph: the chachamim commanded that a person should not teach his daughter Torah because most womens minds aren’t focused, and through this they’ll learn to question (nichnas ba armumis). And whoever teaches her Torah is as if he teaches her immorality. But a person should teach his daughter chumash.”
Now it should be noted that nowhere in this prohibition does it prohibit teaching halacha- in fact it was their obligation to teach their daughters hilchos nidda, tvilah, salting, issur yichud etc. as well as any mitzvos asei not bound by time as well as all lo saasei of Torah and chachamim.
And nowadays at the end of golus, this would include dinim of korbanos etc.
