My friend had m31 and he was facing this same problem. At first he was experiencing 1-2 restarts and then after some more upgrades given by samsung his phone getting restarts in every 5 min of usage. Now he downgraded to Android 10 with powersaver mode to underclock phone's processor. Firstly if you're using SD card then try to remove it and observe and if problem persists then you have to downgrade your device and wait until samsung releases stable version of Android 12 or 13. Their updates feel like Beta version of firmware. Everytime they carve out a major issue. Defend your motherboard from samsung. I saw my friend's M31 Condition and i was shocked what samsung did to that device and you can youtube it , it's the issue facing by majority.
