I have LB installed on Mac running BigSur. I can see built in camera and USB camera I intend to use for LB. It is a HBVCAM FHD camera.
When I select EITHER camera in LB via Tools>Calibrate Camera Lens “choose camera” LB instantly crashes.
“Lightburn Quit Unexpectedly”
MacOS generates the attached report.
I searched this and other forums, but have not seen a solution to this. LB Crash Camera.txt (102.1 KB)
Thanks for any help you can provide.
The crash appears to be deep within the core MacOS A/V libraries, not within LightBurn. I can’t see anything meaningful in the crash info - I just ask for the camera.
Perhaps I skipped a step. I’ll confess I don’t know how to check to see about permission to use the camera.
Since it works with other apps, FaceTime, for instance, that is a good spot to start.
If you check your security settings for camera and microphones, it should be listed there as an allowed application. I have seen it crash before if the app isn’t authorized, though usually you just get a “non working” camera.
no listing for LB at all.
I think next step is likely uninstall LB and reinstall.
I’m on the provisional license, so I don’t know how this works.
Giving It a whirl now
I just plugged a camera into a new M1 Mini running Big Sur, and I get the crash, along with a blurb from the OS saying:
“This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app’s Info.plist must contain a key with a value explaining to the user how the app uses this data”
I’ll have to look up how to do this, but it seems this is the issue.
This may be the path.
I unistalled (deleted) and reinstalled.
Accessing camera from “choose camera” in camera control yields same crash.
No entries or prompts in “security & Privacy” in OS Preferences.
no prompts or asks for permission granting.
Thanks for your assistance.

I’ve made the appropriate change and it no longer crashes my debug version. I’m in the middle of trying to track down a different issue, but I’ll try to get a new build posted with this change soon.
