I think my phal. got crown rot help me try to save it please :(

[Alvaro78]

Hello guys,

Today I went to touch one of my orchids leaves and it fell and I noticed that the part closest to the stem was black and then another leaf dropped and I am now left with 2 leafs and in the center I can see some black.

I feel so dumb because I am always careful with watering and I always remove the water that may be on the leaves or the center and somehow water still got into this one

So I was wondering if you could tell me the chances of it surviving and what could I do to try and save it? Like applying cinnamon or something?

I attach some pictures so you can see the state of it. Thanks a lot for the help!
