@DieselTuner can you check if the steps suggested by @adam1018 here solve it for you as well?

@Sparrow082

You need to do all of these:

Update Microsoft Visual C++ Redistributable (just Google it, grab the latest from Microsoft)

Install RDWorks 8.01.68 or newer — even if you never use it, the libraries matter

Update LightBurn to 2.1 or newer

And the one that’s not obvious at all:

When you send a file to the controller, the filename can only be plain lowercase letters. Nothing else. No spaces, no numbers, no underscores, no capitals. Just letters.

testsquare works. test square, TestSquare, test_1 — all lock up the controller.

Hope this saves someone a few days of frustration.
