Lightburn stopping in the middle of projects

Over the last couple of days I have had several projects that have just stopped in the middle of a project for no apparent reason. I had the same issue happen with two different laser machines the Ortur LM2 20w and my YoraHome 6550 3w. At first I thought it was an Ortur problem until it also happened on my YoraHome. I was reading last night in one of the Facebook groups that others have had the same issue recently and they went back to a previous version of lightburn and it stopped. I have a MacMini, 32GB memory 2018 version of MacMini and Catalina System software version 10.15.7. I have noticed that I am having more issues since I started using the Ortur LM2 vs the YoraHome or at least I thought until it happened on the Yora as well. Since most of the earlier issues are communication issues remaining busy, etc after a job is finished, I am tending to believe it is a USB problem. I am pasting support data into this string and then the gcode after a paragraph end.

When you look at this it says stream completed but the stream was not completed. I am referring to the very end where there were likely 3/4 of the tile done and 1/4 to go when it stopped. This is however the complete string from the end of the day yesterday.

The fact that this is displayed immediately after the ‘stream completed’ message tells me that the USB connection was dropped, then re-established. I would check for a loose USB connection, either at the computer or the laser.
