Sony a7RV as a webcam suddenly lost video

[zeftonic]

We had a meeting that had to be canceled due to the video freezing right before the start of the meeting. I have had this setup for the last two years with no issues. 

I have a Sony a7R V using a USB-C to USB-A cable through a hub with USB-C into my Dell XPS PC. The camera is less than two years old and has a fully charged battery.

To troubleshoot, I made sure Zoom and Sony software were updated. I uninstalled the Sony Imaging Edge software from their site and re-installed Zoom. 

I also tried different USB-C cables, including USB-C to USB-C. I tried different ports on the PC and ensured my Win11 PC was updated.

After trying different settings, when the "USB Connect Mode" comes up on my camera and I select "Remote Shoot," as I've always done, Zoom will only show the Sony Imaging Edge screen and will not display the video output.

I tried the "Live Stream USB" option as a workaround, which immediately works with the 720p/30. So if I get a faster USB 3.2 cable, which I haven't tried, that should work to get the 1080p/30, which we need to display software screens to our clients.

I'm not sure why my Sony and Zoom is not working suddenly. "ILCE-7RM5" comes up other than the "Sony Camera (Imaging Edge)" when I select the "Live Stream USB" option, so I'll use that for now as the 720p/30 seems to work consistently.
