If everything was ok when you laid it up and there were no pending mechanical faults then I would suspect some corrosion has developed in the barrel. This would form a barrier that the rings couldn’t pass. Another possibility, albeit I’ve never seen it on a small engine is that a mouse has crawled in and it’s blocking the piston!

Those cheap endoscope cameras off fleabay that connect to your smart phone can be useful here

Maybe you know someone that has one?
