The Briton surprisingly lost to the world number 77 in the first round and has lamented her defeat at the hands of Serbia player.
Konta who was looking to improve on her semi-final appearances at Australian Open and Wimbledon suffered the very first major upset at the Flushing Meadows.
“It’s definitely not an easy defeat to take – it was a close match,” Konta told BBC Radio 5 live.
“It went to three sets and over two hours. I try to keep a very good perspective on how this sport works and that is there are no easy matches. “First rounds are always tricky and difficult, regardless of the tournament but I guess especially in Slams, so I think that’s for everybody, not just me.
“My opponent dealt with it and I competed until the very last ball, so I can’t be too harsh on myself in that sense, but I’ve definitely got a lot to improve on, which is also a positive thing.”
Konta was, however, full of praise for the unseeded Krunic, “credit needs to be given where it’s due and that’s to how my opponent played,” said Konta.
“I felt that she raised her level of tennis consistently throughout the match, whereas I struggled to maintain that and fluctuated a little bit more.
“That’s a credit to her for playing as freely as she did.”
