Razer Kiyo stopped working

Hey all,

I picked this camera up in March and have been using it with Mac Catalina just fine. I had a meeting this morning and the camera worked but in the next meeting, the camera stop being available in the camera selection, and has started flashing the thin light that normally indicates the camera is in use. The light now flashes on for about 5 seconds and then off for 5.

I've read about resetting PRAM and SMC and have done both, nothing has helped.

Any ideas?
