In-home chine keeps ringing and then ring doorbell pro got dead

Hello all, I installed my ring doorbell following the instruction. At the begining, it works. The video and phone work very well, I can talk to my wife when one of us ring the bell at the door and the other stay home using the app. However, about 1 or 2 hours after that, my in-home chime kept ringing, but no one pressed the button of ring doorbell pro at that time. I couldn't figure out the cause and couldn't fix the issue, either. So I turned off the power and then turned on. After that the in-home chime didn't ring. And the doorbell pro was offline, I attempted to setup the device in the app, but the doorbell blue light was on and was blinking in the 10-11 clock position. I learnt from Search Engine bing that doorbell was charging so I stopped my attempts and waited. A few minutes later, the doorbell pro was online in the app, however, the chime started to repeately ring again. I tried various ways in the app, and no one was working. And later on, the chime stopped ring and the ring doorbell pro was offline again. This time it is totally powered off. When I push the button of ring doorbell pro, the chime doesn't ring. It looks that both doorbell pro and chime are dead now. Would you please share me some tips on resolve the issue? I peresonally suspect that something might be wrong with the power kid v2 installation. But at the begining it worked.
