Crash when camera loads

[laguel (Gabriel Amaral)]

Hello, I’m installing a USB camera to control my laser, in Windows in the camera application I can see the image perfectly, but when I open Lightburn and try to view the camera, the program crashes and clouse.

I also performed tests trying to run the program as administrator and also reset to default layout.

I also tried to disable the notebook’s onboard camera, but the same problem occurs.

I recorded a short video showing the problem.

Hi Gabriel - please start by reviewing the guidance here, and let us know how that goes: Getting your camera to work in the hellscape of Windows

Hi, thanks for replying.

I checked anti-virus software and even disabled it.

I checked Windows security settings including Lightburn appears in the list for having accessed the camera recently.

I also tried running the program in compatibility mode with Windows 8, and then with w8 and ADM,

Unfortunately all the results were the same as in the video.

Are there any other tests or adjustments I can perform?

Today I had the opportunity to test another computer, with Windows 10 x64, with a trial version of the test program, the behavior was exactly the same when I tried to access the camera, I also performed the tests requested above on that other machine, but the result it was the same.

I was having trouble getting Lightburn to display the picture from my new “webcam”. The camera worked outside of LB and LB would recognize the camera but nothing else–No picture, no setup options. I looked through the settings and found that changing the setting in the lower left from “Custom Camera System” to “Default Capture System” did the trick. You do have to end LB and restart but when I did, LB showed the picture, and I was able to start the camera setup routine.

I’m running Windows 11 Pro on a mini PC. The picture below was after restarting LB.
