From the debate at the time, I think it was a timing thing too, you jump too soon you’re an ethereal hyperdrive ship that passes through them, you jump too late their shields are up and /or their tractor beam is stopping you (for small kamikaze ships).

That’s why I think Leia should have done it and for any non force user it would have been next to impossible etc. Plus it completes Kylo’s ascension that both his parents are dead.
