Redmi K70 Pro freezes

[DarkSider2442]

I recently bought a redmi k70 pro and in some games (tested in honkai star rail and afk journey) after ~10 minutes the phone freezes with a loud squeak. When trying to reboot it freezes on the logo or on the desktop, after a few minutes it turns on normally. Perhaps the problem is overheating, but in afk, unlike honkai, it is barely warm, in simpler games it works without problems. What could be wrong with it? :c
