Camera - Black screen

[Managely]

I have the camera for the zoom meeting - BUT in stead of showing me it is a full black window - no image, no background possible - it just stays black. I have given zoom access to the camera in my settings, I have reinstalled zoom, but it remains black. I have daily meetings, it never was an issue. It just suddenly is there. Is in on a Mac Book Pro - Anyone nows the solutions? Any feedback appreciated.
