- Unexpected crashes: The app tends to crash at some point after opening a session/upon closing a session.
Is anything printed to the terminal when it crashes (if you launch the app from the command line)?

@rolfbjarne when launching from command line, this is the output that gets displayed. the crash happened right after all the media files were loaded in, but afaik no explicit info about the crash..

That's really weird, something more useful should have been printed to the terminal.
Can you zip up /Users/harithamohan/mac-samples/CameraBrowser/CameraBrowserSample/bin/Debug/net7.0-macos/osx-x64/CameraBrowserSample.app and attach it here?

@rolfbjarne The compressed file is too large to attach here, but I went ahead and just pushed my latest changes to the branch. Just a note the pr is still a wip- I need to integrate the updated changes with the updated thumbnail selector. So it might be easier to debug this once the pr lands?

Unfortunately neither help much :/ it seems to be a problem with key-value observation, but it might take a while to track it down (I would simplify the app as much as possible, to try to create a minimised sample, and then hopefully end up understanding what's happening in the process).
