Upgraded to 16.0.1 and Camera not working

I upgraded to the latest 16.0.1 version on Windows 11. The “Update Overlay” remains greyed out. The camera is still a selectable option, I can’t run a calibration because “Next” is greyed out as well. I can see the camera in Windows 11 going into camera settings so Windows see the camera as working fine. I enabled the debug logs and getting:

I literally changed nothing else about my current configuration. Permissions are also set in Windows to allow LIghtburn to access/use the camera. Please help, thanks!

Regarding Win11 permissions recheck if you gave permissions to the camera microphone.
Sometimes Win11 and Win10 is a bit “wavy” with settings changing the default Apps linked to file types, This never happened with Win7.
Worth a check.
Also check if the camera drivers became corrupted, maybe reinstalling them.

Yep, already checked all that. If the drivers were corrupted, the camera wouldn’t be working in Windows. Will have to keep digging I guess. Seems common for new update installs that things like this happen for some reason. Very frustrating!

You could also try importing back your camera settings by right-click inside the
CameraControl window.

Yea unfortunately on my end, update overlay, trace, and settings are all greyed out. So I can’t right click on settings to do that. It finds my camera because I did a test of unplugging the machine from my computer. The camera disappears as a selectable option. Then when I plug it back in, the camera shows again as a selectable option. It’s just not communicating with it beyond that.

Even without any camera selected if you right-click inside the Camera window or Camera top bar…
Sorry by underlining the settings button, I mistakenly took you in the wrong direction.

Scratch that, just can’t right click on the button itself. Just don’t have any backed up settings to import.

However I was able to get it working by selecting Default Camera System instead of Custom Camera in the Settings > Camera Capture System

Thanks for your assistance by the way!

Yes, those were the next steps. It was just to avoid calibrating the camera again.
I’m glad everything’s working now.


Yea all good! Just weird how installing a minor update messed that all up. I didn’t have that issue going from 1.5 to 1.6. Although, stranger things have happened.
