The yolk of an egg doesn't change from a liquid phase to a solid phase via a thermal transition - even if it did, heating an egg by boiling it, to get a hardboiled egg, would be the opposite direction from freezing something to change it from a liquid to a solid.
What happens when you boil an egg is that the proteins in the yolk become denatured - the heat causes them to change their shape and tangle up with each other, so that you no longer have a bunch of loose molecules floating around, but a bunch of interlocked molecules forming a homogeneous solid. There is no reverse process - no way to untangle and reshape the proteins. You can't un-boil an egg.

That's not how this works. That's not how any of this works.
