Why isn't my ring stick up camera turning on

My ring stick up camera which had stopped working and it says that the camera is offline and the rest of the other devices in my house that are ring products are working fine and I have another stick up camera that is working fine but this one isn’t. Also it would not turn on or reconnect back to my wifi. I have charged my battery for my ring stick up camera to 100% and it also shows green on the battery and no red. When I insert the battery into the camera the blue lights up for like 3 or 4 seconds and then stop. Also I removed the device off of my ring app to reconnect it and when I clicked and also held down on the orange button on the bottom of my camera the blue light wouldn’t flash blue and the battery is full. No matter how many times I charged and held the orange button it still wouldn’t flash blue I’m thinking that my camera is broken even tho I just bought it last week. So I posted this on this website to get help from somebody.
