crown rot?

[OrchidBlossomss]

i really need some help with my orchid. it's the first time one had crown rot and i didn't know. the plant was growing a keiki that i removed too early because i thought it had own roots but it didn't. the rot is dry and i've read on the internet that i should sprinkle some cinnamon. i'm very scared that neither the plant or the keiki will survive. please help me with an advice!!!!
