Attempt Number: 3
Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
We need to free car3 from being blocked to reach the goal state effectively. Moving car0 to curb_0 (since it is clear) achieves this and aligns with the final goal state positioning for car0.

New State Description:
Curb_0: Car_0 is parked and clear. Curb_1: Car_1 is parked and clear. Curb_2: Car_2 is parked and clear. Curb_3: Car_3 is parked and clear. Car_2: Still parked at Curb_2 and clear. Car_1: Still parked at Curb_1 and clear. Car_0: Now parked at Curb_0 and clear. Car_3: Now clear at Curb_3 after car_0 moved.

Action Chosen:
(move-car-to-curb car_0 car_3 curb_0)
