Hi, I have the same issue as the user "agfinco" :

"Hello everyone,

I just bought a razer kiyo 1,5 years ago, I'm using it as my daily camera to work. I do meetings and thats all, usually the camera is turned on at most for 1 hour for each meeting. Most of the time it is turned on only for 15-30 minutes.

Today I was in a call and decided to turn the ring light on, which is something that I haven't done in while. It turned on normally, however some minutes after turned on the right light started to flicker, so I tried to turn it of, but it didn't turn off.

So I disconnected the USB cable from the hub connected again, after doing that the camera was recognised by the google meets meet, however after trying to choose it and turn it on, it turned the "on/off" LED on the image popped, but a few seconds later the on/off LED started turning off, but different from normal, it was turning off like a capacitor discharge.

Then the computer doesn't recognise the camera anymore, I tried different USB ports, tried let it disconnected for sometime and connect again, I also tried to connect to a different computer. Currently I was using it with a Mac Silicon chip connected though a TP-Link hub, connected to a USB-A to USB-C adapter connected to the Mac. I tried to connect it directly to the USB-A from my windows machine. When I open razer synapse on it, the camera was recognised, however after trying to open it and access, the same behaviour happened, the camera turned on for a few seconds, and became unreachable.

Windows showed me a message informing that the USB device presented a malfunction and can't be reached anymore. After that looks like the camera was connecting and disconnecting from windows, this error message was popping a lot of times, and that sound of connecting a USB device to windows was sounding repeatedly.

Any clue? The camera is just broke after 1,5 years of usage? 

Best regards"

Exactly the same issue, after circa the same time of bought, I started to lose confidence in razer products, I already had problems with a blackwidow v3 that stopped responding the keys after a year and a half, with the dongle of a nari ultimate, and I expected to have a good durability and razer's response is that if I do not have an invoice where I prove that I bought the product at an official distributor (since I live in Argentina and here there is none) they can not do anything but clearly more people is having the same problem with the same products so is obviously a problem of their products and they are not responsible, I need please some kind of answer.

Thanks in advance
