Galaxy s21 5G Keeps restarting at random

[Snowly]

Hi

I'm in desperate need of help with my phone restarting at random. 

The phone was working fine until 2 One UI updates ago. 

The first One Ui update that made the phone restart at random i could fix by going into settings ->apps -> press the three dots in the top right corner and then press reset app settings (Third choice from the top) 

This fixes the problem. 

But now since I've downloaded the latest one ui 6.1 the problem has reappeared... and this fix I mentioned earlier doesn't work.

How should I proceed, is there anything I could do? 

Thank for reading and trying to help me

Try restarting into recovery menu and there wipe cache parition and then boot back and see if the random restarts stops. If it does then old data in cache partition was causing apps to multiple restarting themselves many times which caused your phone to all of sudden reboot on it's own.
