I think the problem is with this line:

System.setProperty("webdriver.gecko.driver", "C:\Users\KSaraswathiChowdary\Documents\softwares\geckodriver-v0.24.0-win64.exe");

Backslashes (\) are used for escape sequence. Try this:

System.setProperty("webdriver.gecko.driver", "C:\\Users\\KSaraswathiChowdary\\Documents\\softwares\\geckodriver-v0.24.0-win64.exe");

Problem is not resolved with is this line
"Facing error path does not exist"
System.setProperty("webdriver.gecko.driver", "C:\\Users\\KSaraswathiChowdary\\Documents\\softwares\\geckodriver-v0.24.0-win64.exe");

In essence, the error is telling you that somewhere, you have a backslash that does not belong, and it's escaping a character that is not in the list it's shown you.

Try using a valid escape sequence such as a backslash character.

Alternatively, you should use forward slashes, those are filesystem independent and will work whether you run your Java program on Windows, Mac, Linux or elsewhere. 

"D:/workbox/Online Store/geckodriver.exe"
