Frankly, I am actually at a loss at what else could be done and it's heartbreaking.

Yeah, I don't think any of the typical political or economic pressure tactics will have any effect on the Taliban. The only thing that will end the oppression of women in Afghanistan right now is a direct military intervention to remove the Taliban from authority, followed by a sustained presence long enough to substantially change the culture. A new generation would need to be born and grow up with a different value structure that treats women as equals (so like, 50 years minimum). And that means running the country's public institutions, rewriting its laws, enforcing justice and re-educating/indoctrinating its population, which is morally ambiguous at best.

I don't think there is enough united global will to support that, and it's an ethical minefield of one culture imposing its beliefs on another (which has some nasty parallels with the imperialist/colonialist days). There's no fix that doesnt involve violence that I can see.
