Your sewing machine could also get stuck if the bobbin lacks proper synchronization. This could happen due to various reasons:
- The device must have been dropped or knocked over
- Malfunction may occur due to excess usage
- Dust or lint must have clogged the device

Needle Not Fixed Right or it is Deformed
If the needle is bent or it fixed properly, it could hit the bobbin case while sewing and stall the project midway.
