Cell Zone Error on Simulation

My project consists of an aerodynamic analysis of a wing of an F1 car.

Upon creating an external flow region and attempting to mesh, it kept giving me an error regarding the intersection of cell zone. I tried changing anything I thought was problematic and still got nowhere. Therefore, I was wondering if someone could help me by reviewing my simulation.

Hello d10
