Concentration

does a change in concentration cause Kc to change?

If all other conditions remain the same, the equilibrium constant won't change

Since it is a constant, concentration of the product or reactant changing like for example adding more reactant or product will not change Kc, instead the system will shift accordingly to reach equilibrium again and that will happen when the system reaches the Kc ratio. The only thing that can affect Kc is a change in temperature.

If it is only a change in concentration, Kc won't change, the equilibrium state, at least right when the concentration is added, will be different, but it will still tend to the same equilibrium constant

A change in concentration does not cause Kc to change because equilibrium adjusts until the standard Kc rate is met. However, an increase in temperature will cause Kc to shift towards the reactants and vice versa.
