My MacBook Air M3 has now started freezing few applications

"I recently purchased a MacBook M3 (newly launched) from Islamabad, Pakistan, with a one-year warranty. The device was brand new, and I have been using it for three months. Occasionally, it hangs while I’m working, particularly when using applications like Pages, Keynote, or Numbers. This doesn’t happen often, but it’s noticeable. Could this indicate a fault, or is it a normal occurrence? I would appreciate any guidance or solutions. Thank you!"
