Kand,
I’ve had PLC so bad it affected fruit and the fruit never looked like that. I’ve had freeze damage multiple times at various stages on peaches and never seen them look like that. I’ve had broadleaf herbicide damage and the fruit looks exactly like that.
The fruit elongates at the apex end (some peaches elongate along the suture). Those points of elongation ripen and rot before the rest of the fruit can ripen.
If you aren’t using mulch or manure then either you have leftover soil herbicide residue from a few years ago, or they have sprayed more recently and you were unaware. If you didn’t apply herbicide yourself, then someone else applied it in some way to your soil close to those trees without your knowledge, or it washed in on the soil close to the trees through rain from another property.
Normally, I don’t try to be so confident about diagnosis, but this is a case which perfectly matches symptoms of herbicide damage on peach fruit.
