There certainly are more experienced people than me who would likely offer a wiser reply, but I would guess that the saw might well have simply quickly froze up with no damage to the crank bearings or anything else besides the p and c.
After thoroughly blowing out and cleaning the crankcase and parts within, check the crank movement. If it seems good, why not go for it with a new p and c. When you do install the new piston on the crank, be mindful of the circlips position that holds the piston on the crank pin. The curly q should either be in the up or down position in it's seat, not sideways, or it's said that the clip can fly out. I had a clip either break or fly out once on a real cool modified saw that I had put a lot of work into and was getting real good use from, rendering both the piston and cylinder damaged to uselessness.
Bring that saw back to life!
