Can Potential energy be stored without any external force?

Potential energy by definition is defined as the energy of an object or a system due to the position of the body or the arrangement of the particles of the system.
Now potential energy can be stored within a system because of tension in the body, or compression in the body. So, lets consider your example of sling shot, when the rubber band is not stretched, it still has some potential energy in it because of its position. When you apply force to stretch it, you further increase its potential energy and then when you release it, that gets converted to kinetic energy to reach back to its equilibrium state. But, in this problem also, when no force was applied initially, there was some energy stored in the system because of its position or in other words, because of the arrangement of molecules in a certain manner.
