If that’s the case then it might be worthwhile to try resetting your prefs file.
Check here for notes on how to do that:
Reset LightBurn to factory settings? - FAQ - LightBurn Software Forum
Before doing this I’d suggest:
- Take a backup of prefs using Files->Export Prefs
- Take a backup of camera settings in the Camera Control window
- Take a backup of your device by pushing the Laser window Devices button and exporting from there
The prefs file will include everything but if you wanted to only restore the camera or laser device you could.
