Answer 1

import java.io.File;
import java.nio.file.Files;
...
driver.get("https://youtube.com");
WebElement start = driver.findElement(By.cssSelector("div#start"));
File file = start.getScreenshotAs(OutputType.FILE);
Files.copy(file.toPath(), Path.of("/tmp/start.png"));

P.S. - The issue that might prevent your file to be saved is that you're trying to save it to root of C drive. Try to save it to some folder.
