MacBook Pro M4 keep restarting multiple times daily even with fresh os

Got it on the release date , was working fine , suddenly last week while I'm into Google meet season it hang for couple of seconds then restarted then done it for couple of times , since then I tried to uninstall remove most of the apps to just check what causes it as apple support chat suggest it's apps issue , then I took it to services center ( we don't have direct apple stores here ) , so the run some hardware diagnostic and he says hardware looks fine , but he suggested to do full disk erase and then install fresh os , which i did and even select to not restore anything. So directly after setup the device name and user when I logged in I just click on setting it crashed and restart again - frsh os with no any 3rd party or anything other than connect to my wifi-. I toke it back to store they says they will do manual checking and call ofntheybfind anything.

Any suggestions ? Would it be hardware ?

I bought it from jarir jarir.com
