"No video capture devices were found. My Mac book prod camera has not been working for a long time, since 2020. I am using 13-inch, 2018, Four Thunderbolt 3 Ports. In the system information the Hardware Camera shows - No video capture devices were found. I tried these, didn't work Reset NVRAM or PRAM Reset SMC Updated Mac OS. But it still did not work.?"

To the OP and ALL participants:
Troubleshooting a Crashing Hardware:
A. Add Camera as a Login Item:
What happens when you add Activity Monitor as a Login Item? Add it as such, log out, and then log back in, seeing if you still get this error. Go Here: Open Items Automatically when you Log In on Mac - Apple Support
No success?
B. Reinstall the macOS:
The iSight Camera is part of the mac. So, one option would be to reinstall the macOS to fix any bugs in this hardware's configuration. Nothing would be lost. It's just that misplaced items would be placed back to where they should be and corrupt system files would be replaced by clean files. Go Here: Reinstall macOS - Apple Support. Boot into Recovery Mode (Intel or Silicon). Important: Prior to installing an update or performing a reinstallation, to prevent data loss, be sure to Back up your Mac with Time Machine.
