 Blynk.virtualWrite(V0, data);
  Serial.print("Pin A0: ");
  Serial.println(data);


  if(data > 20){
    //Blynk.email("test@gmail.com", "Alert", "Gas Leakage Detected!");

It looks like you have the unofficial Blynk for Chinese library installed, probably alongside a Blynk IoT library.
Delete the Blynk for Chinese library, and make sure your Blynk libray is fully up to date then recompile.

BTW, when you post serial output or compiler error messages you should use triple backticks in the same way you do when posting code.

Also, Blynk-cloud.com was the url for the legacy servers, which were decommissioned at the beginning of the year.
