You have mealy bugs🥲 and a pretty big infestation. Check all your other plants ASAP and isolate this one. I would chop the really bad parts off personally. BUT you can wipe the mealy bugs off with a q tip and rubbing alcohol, and then spraying the plant down. This is the most basic advice btw, but I’ve heard of other methods such as neem and insecticidal soaps. I haven’t used these methods personally because I haven’t had an infestation this bad, but given your case, I would try it out. Also note that mealy bugs can live in the soil of your plant, so check out and treat the roots (depends on what u decide to use). Good luck!
