Apple watch SE keeps freezing

My Apple watch SE keeps freezing. The screen will be blank, I put it on the charger sometimes the Apple symbol will come up or sometimes either a red squiggly line or a green squiggly line will come up. A few minutes later it will work fine. It is up to date, I’ve tried unpairing and pairing it again. No luck!! Anybody have this happen? Just got the watch in November 2021
