You may have been rather unlucky and the engine has stopped at TDC, This means that two pistons are at the top of their stroke and two at the bottom.
With only a little corrosion/old hard carbon in the bore it can be very difficult to get the engine moving now the rods are vertical an have little leverage.
Had an engine like this once and tried all the tricks above but in the end it was head off and whack the high pistons [ block of wood on top ] until they came free. Cleaned it up and wind it over on the starter a good bit, Back together and went on for years.
As Wimblowdriver says a socket and bar on the crank bolt and rock it back and fore. May get it moving after a soak.

We have to acknowledge that the engine was turning over before, I can't see that the bores are too rusty and pistons seized... this is a strange one. Tottot's suggestion above is intriguing and worth thinking about. If it were mine I would be taking the head off and seeing what there is to see: what condition are the bores, are the valves intact and free etc.
Is there any movement at all when you try to lever the ring gear? Even if only a tiny bit?

I'd stick it in reverse and get a couple of mates to try pushing it forward a couple of feet.

When you were starting it with starter motor you probably depressed the clutch, could there be an issue with gearbox. l would try the starter motor again with clutch depressed before taking engine apart.

Have you tried rocking/pushing it in gear?
