After you reseat the foot and rethread the machine, try things out by turning the handwheel. As you turn the wheel and the needle moves slowly, you will be able to see if it will hit the foot or go through.
I would even walk the unit through a cycle without a needle just to see what the foot is doing.
Did you fully rethread your machine?
Did you increase the thread length by a bit because now, the foot has to pull the entire sandwich through?
Is your machine tension automatically adjusted?
