Macbook air m1 (2020) shutdown issue- getting restarted while shutdown

Hello guys, I am facing issue while trying to shutdown the laptop using shutdown option in screen.Problem is after shutdown down it is getting restarted on its own.I had to hard press power button to avoid this ,but earlier this problem with restarting was not there. The OS(Sonoma) is updated. Has anyone faced similar issue or can tell how to remove this problem?
