MacBook Pro Retina mid 2012. The error "No connected camera" could be "solved" by "sudo killall VDCAssistant" years ago.
Today the error comes again but VDCAssistant cannot be killed. I have restarted the MBP several times but no luck.
The camera works if I login High Sierra with another (admin) account.
Question: how to make it work for my daily account?

Sounds like a conflict with something that is running in your personal account.
Try logging into your account holding down the shift key. Hold it until everything has settled, it can take a minute or two. This will prevent login apps from running.
See if the problem remains.
