LightBurn should not crash. Please provide any reports presented, so we can track down what might be happening. If possible, it is also very helpful if you can provide step-by-step instructions to reproduce what you are observing.
What are you doing when you notice disconnection? What are you doing when you get a crash? As much detail as possible helps us try to reproduce here.
To help sort for your current needs, you can always revert to an earlier version. All previous versions of LightBurn are available in our version archive, here: Releases · LightBurnSoftware/deployment · GitHub
