Might have got it's own ants nest. That's not too good for a plant. If it is, the ants will be frantically running around carrying eggs, trying to rescue them when you disturb the nest. Vine weevil larvae are bigger than ants eggs. Also consider slug/snail eggs, like small white ballbearings.
I'd get it out of the pot, and separate the roots and remove whatever is living in there. Repot in something free draining, add a bit of grit. Water in to settle the compost and see what happens. It doesn't want to dry out but lay off the excessive watering.
Then speak to it nicely and hope it responds
