I would put a disable input node right after the damage check, before you start the dying animation. Not the boolean check you’ve put in, but the actual “Disable Input” node. Then a “Set Input Mode UI” after the dead screen shows up so the player can interact with it.
It doesn’t have anything to do with the dodge roll. Though, I see that you’re using a bool to prevent double inputs, and you have not put a branch on the dodge roll action to check if Inputs are allowed.
