ESP32 C mini didn't boot up

I use esp32 c6 mini in my IOT project. At first, it works normally when I use it with LiPo battery 3.7v but then Its blackout and didn't boot up when I power it. I use my multimeter to check that is power is normally with bat pin and it seem normal. And 3.3v pin can still use. Did it have another way to check where the problem is? or it already broken. 😞
