Hi Praveen,
There is no error there in your screenshot
Check your test case for Close All Browsers, Close Browser or Close Window, if you have one of those it could be expected the browser is closed at the end of the test?
This is quite an old thread so your issue might be different to the OP, it’s best you create your own thread, and provide details about what you are getting, what you expected, an example test that shows the issue (if you can’t post the real test) and logs (in text not screenshots, is best) showing any errors you are getting
Unfortunately you haven’t provided any useful information that would help anyone figure out your problem,
Dave.
