macOS Screen sharing does not work - Security settings issue

Since last week screen sharing is not working anymore. When in a meeting hosted by me (licensed user) the app asks to update the security settings in macOS and allow zoom to record screen. I accepted, restarted zoom. etc 

Still the zoom options will not adapt, so I can share a window. 

I've updated, deleted & reinstalled zoom, rebooted, changed different settings of screen sharing... and run out of ideas how to fix this. 

I am using macOS Big Sur 11.6.2 on a iMac (24-inch, M1, 2021) with zoom 5.9.3 (4239)

Any ideas out there?
