Emergency mode...?

So I downloaded the latest image today, burned it with Apple PiBaker to a 16gb card, then dropped it into my new Pi4 2gb - It boots to the Volumio logo, then crashes out to “Welcome to emergency mode!”

I’m stuck - I can’t find anything in the FAQ or help about this - any ideas?
Thanks!

what do you have on your pi hats ect… and how many amps and voltage do you give it…
