Logitech StreamCam / Logitech Capture disappeared

[skjdfh]

I've had a Logitech StreamCam as my Video Capture Device. Recently it's disappeared - possibly after a Windows update. I've created a new Video Capture Device (using Logitech Stream Cam - Logitech Capture is not listed) but still nothing. I can see the frame for the image, but it's blank. Only one Scene is working. Logitech Capture is running and is working. There are no other apps running or using the camera. Windows is fully up to date, as is OBS. I've white-listed OBS on Windows Defender. I've closed everything and restarted. I've run OBS as Admin. I've rebooted. If I close the Stream Cam software and then toggle on and off the view symbol I can see the image. Any other ideas, please?
