I recently enrolled in masters in AI after doing my bachelor in CS, I'm overwhelmed how to start research
TL;DR. Search this forum, and beyond, for impostor syndrome: What you're experiencing is perfectly normal.
At masters-level, you're just entering the amphitheatre arena. Of course everyone looks better, you haven't started yet. I see outstanding papers published round the clock, that's great! You're looking in the right places, finding the best stuff. It really makes me feel how anything I would do would even match the lowest standard worthy of publishing, that's impostor syndrome. Hang around, absorb the knowledge, learn how to compete.
[N]ot to mention the single biggest problem I don't have a problem in hand, many students get handed problems by their advisors, only later do they identify their own problems.
Look in the mirror, ask yourself, do I want to do research? If the answer is yes, go learn how to do it. Don't worry about not being able today.
