Iphone 11 pro Max keep restarting

Greetings,

i have a problem with my iPhone (iPhone 11 pro max)

it keeps restarting and when it opens it just opens for five minutes or even less and freezes (touch and screen no response) and restart again sometimes screen goes black sometimes i got the loop sign sometimes ‏ logo

the problem is 2 weeks ago and still the same

i tried

• Force restarting
• reset network settings
• reset all settings
• i removed the sim card
• i deleted many apps (as I could when it opened for 5 mins)
• Tried to update it it was 16.1 now it’s 16.1.1 (same problem )
• it can’t update to the new update (16.1.2)
• i even bought a iCloud storage (200gb)
• i even bought a subscription on (IMyfone) and nothing happened the same problem

* nothing helped and nothing happened after all of those

**btw it suddenly got that problem the day before i have that problem it was working well

• IPhone 11 pro max
• 256 GB
• ios 16.1.1
• battery health is 84%
