S21 Ultra Restarting after latest update

[luk34dd0]

I'm just wondering if anyone else is having issues with their S21 Ultra after the latest update?

My phone has started to randomly restart. It doesn't seem to be any app causing this.

I have had 2 random restarts since I updated a week or so ago
