I'm encountering an error when running dfx deploy. After executing the command, an error appears. I'm new to this and still learning. I’d appreciate any help!

I tried running dfx start --clean, changing the port, and checking if it's in use, but the error still persists. I also attempted to unblock it through the firewall, but it's still not working. I’m not sure what else to do—can anyone help me
