Using migration assistant and it’s taking 21 hours at starting up

I’m migrating from mba 2020 to mba 2024, at first i tried via WiFi but like everyone else it was taking long. I needed to used my current laptop for work purposes so i been trying to use migration periodically. I’ve contacted Apple for assistance but they’ve said just leave it. I’ve tried it again with thunderbolt cable at 6:30pm and so far it’s still ‘starting up…’ after 21 hours. I understand it’s depends on the amount of information that needs to be transferred but I need it sorted at least by Monday for work
