Alarm 3 Error (new)

I’ve been using Lightburn with my LM 2 15W since last summer with no issues at all. I just upgraded to the current version and now, when I start to burn, the laser head goes to the starting point but does not proceed; it just moves/jogs back and forth a few mm. continuously from the initial position. I am getting the following error message (see screen cap for more details):

Reset while in motion. Grbl cannot guarantee position. Lost steps are likely. Re-homing is highly recommended.
Ortur Laser Master 2 Ready!
OLF 137.
Grbl 1.1f [’$’ for help]
[MSG:’$H’|’$X’ to unlock]
[MSG:Caution: Unlocked]

I did review the other Alarm 3 issue posted in the forum but that didn’t seem to apply. Please advise - thanks.
