Crown separated from roots??

[Candimac]

Hi Everyone. I'm kind of new to orchids in comparison. I have a few phals that I've had for a few years that consistently rebloom so I'm familiar with their care, but never ran into what I'm about to describe.

I have a mini phal, who was done flowering and I wanted to repot it in some fresh medium. I carefully removed the plant from the pot/medium and as I was inspecting the roots the crown broke right off. I was barely touching it, and the whole thing just fell into my hand. I'm now left with a bunch of healthy roots and two leaves.

My questions are:

How could this have happened?

Is there any probablility of saving this plant? Can I cross my fingers and put the crown in some medium hoping it sprouts some roots? (And since there are no leaves to bring energy to the plant, I'm assuming the roots are toast- going in the compost.

Thanks and I really appreciate your feedback!
