other info:
The camera can run fine when the app run in iOS device

Start by running the linked reproduction project on an M1 Mac with the MacCatalyst debug configuration and compare its CameraView behavior with the working iOS-device case. Trace where CameraView reports “No camera available on device,” then verify the platform-specific camera setup and permissions. Done means the camera is discoverable and usable on MacCatalyst without regressing iOS behavior.
