My screen frozes in the middle of fight

Hello, i have a samsung A51 mobile, last month i had a problem with AQ (when i start fight there is 10 to 20 second frozen screen till match starts but that is fixed) now when i play arena or any content in the game, in the middle of the fight i just got screen frezze for 2 or 3 secs and then fight continues. and its a often issue that i am facing, this month this is really often. couple month back it happend but rarely, now its really annoying. Hope you can help me and fix it somehow.
