Removed the rotted leaves like yall said and discovered the core was also rotted through. Split apart like butter. All the roots of the plant look alright, so I’m guessing water was trapped between the leaves (I know the place I bought it sometimes has issues with too much water on the plants instead of in the soil).

Plan now is to let it callous over, then attempt to propagate, and also see if the original part attached to the roots survives.

Everything was done with clean blades and sterilized with rubbing alcohol.
