Camera is Stuttering. Help please/ solutions?

Unit: Samsung Galaxy A54 (since release) so less than 3 years. I do not upgrade tech often since I have my studies to attend to.

Recently napapansin ko mag stutter ang phone camera if iopen ko yung back camera (Camera mismo or Instagram). There was an instance where I tried to take a picture using Instagram - due to so much stuttering, the phone restarted on its own. This happened not only once, but twice. So far as of writing this post, naga stutter pa din ang cam pero not as severe na nagarestart na ang phone. Pa advice naman po ano gawin ko dito, I think it's too early to replace my phone kahit may credit card naman ako.
