this is exactly the problem. It will not happen with your machines that have metal bobbins, only the plastic. It gets hot and out of shape. Wind it slower next tiime.
For this stuck bobbin, pull off the thread. You can save it if you wind it on another bobbin with an external winder. Then THROW THAT BOBBIN AWAY. It is warped and will not work.
