OSX no cam/mic access dialogue

Hej all,
 
When I deploy a new release of my software (which uses audio and video capture) after installation on a user's OSX machine it asks for permissions to access the mic and the camera. When not enabled sound capture does not work and video even crashes – when enabled all is fine. So this dialogue is really important to the user.
 
However, in some cases the new deployed version does not ask this question anymore and as a result the user manually has to change the security settings. Otherwise the permissions stick to the previous version.
 
For some reason I discover this strange behavior again after deploying with the new Qt6.2 but I don't know if it's really related. As a consequence I compiled the camera example (Qt6.2) and ran it via clicking on the app icon (rather than running it from the console which per se has cam access). Also here it did not ask for allowing cam access and then the app crashed.

I am not 100% certain if this is a bug so I wonder if you can reconstruct this issue.

Thanks,

best

Alex
