Razer Kiyo Pro Ultra not connecting: Intermittent connection loop

After less than 6 months, my camera started having connection issues today.  It will show up momentarily as in option in Synapse and Zoom, but then disconnects.  Again and again on a loop.  Is this an issue caused by Synapse 4 release?  I have already tried all the usual suspects to fix this.  Is my camera bricked?

I have confirmed the issue is not related to drivers or Synapse 4. Windows detects the Kiyo Pro Ultra under Cameras, the LED flashes when attempting to start video, and then the device immediately fails to initialize the camera pipeline. I tested with the generic USB Video Device driver in Windows and receive the same error (0xA00F4241 <CameraSwitchFailed>).

I also disabled/re-enabled the device, rebooted, tried multiple USB 3 ports directly on the motherboard, and tested with and without Synapse. Synapse briefly detects the camera but has the same failure to start video. Zoom and Windows Camera both fail to start the video stream even though the device enumerates normally.

The pattern seems consistent with internal hardware failure that has been reported by other users. If there are any known firmware recovery steps I should try before assuming the unit has failed, please let me know. Otherwise, I believe the camera may be defective. I have already opened a support ticket, but wanted to update here for visibility in case others are experiencing the same symptoms after the recent Synapse update.

Thanks.
