I am trying to use CamLink 4K, connected to a well-configured 2018 MacBook Pro (running Catalina 10.15.7, 19H15) with Apple’s USB-A to USB-C adapter, with mixed results. I am finding that the CamLink 4K starts out working fine, but sometimes goes blank/black as I continue to use the Mac. When this happens, my other two webcams (the “FaceTime HD Camera” built-in the MacBook Pro and the “LG UltraFine Camera” built in my external monitor) continue to work fine. Only the CamLink 4K goes dead. The CamLink 4K is still listed as a video source, but no video is being delivered. I am using it connected to a Sony a7Rii, but have the same problem with a7Riv.
Reading this Reddit post, How I finally got my Cam Link 4K to work reliably w Macbook Pro, it looks like I'm not the only user to struggle with this, and the conclusion there is not terribly satisfactory. I am trying their counsel to not have other USB devices connected in the nearby port, which seems to delay how quickly the CamLink gives out on me (but it eventually does). Sometimes disconnecting and reconnecting seems to fix it. Sometimes I seem to have to resort to a reboot.

If anyone if familiar with this sort of problem, that would be
