Lightburn locking up and not responding

My Lightburn program keeps locking up and not responding. I have the latest version running on windows 10. Does anyone have any solutions?

‘Not responding’ may be that the computer is getting bogged down with a big file. If you’re willing to share the LightBurn project file (lbrn / lbrn2) publicly, feel free to post it here.

If you’d like to share it confidentially for review or comment you’re welcome to send it to me privately or email it to
