Macbook Pro, 13 inch, M1, 2020. macOS Tahoe 26.4.1.
Camera is no longer recognized: "No video capture devices were found" under Hardware-->Camera in System Information.
As a consequence, Zoom, FaceTime, and other software do not have camera option
and, instead, attempt to connect to iPhone camera. The camera used to work just fine; it seems that it stopped working after last macOS update, but I couldn't really tell as I don't use the camera in a daily basis.
Any info is greatly appreciated. And for Apple people: what the heck, man?
Have you shut down and restarted more than once since your "after macOS update"...(?)
>Shut Down
System Info is the camera hardware recognized(?) if not you have a hardware failure.
