Esp32c serial screen works but serial commands wont work

This question is frequently answered. Since you didn’t search, we can guess you’re using Arduino.

Enabling USB CDC on Boot on ESP32-C3 Devkit

Your program code will only output “Hello World” once at boot. It can very well be that PlatformIO only connects to the created serialport after it has already output the text. To make a fair comparison, you should at least print the text continously. while(1) { printf("Hello, world!\n"); vTaskDelay(1000 / portTICK_PERIOD_MS); }
