Hi! Thank you for reporting this exception.
It appears to have been caused by the .NET framework system serial driver, not directly by LaserGRBL. Unfortunately, since it is external code, it is difficult for me to catch this error.

I have already received a couple of reports, which seemed to limit the problem to PCs with Windows 7, but apparently there is also on your PC that has Windows 10.

I would really like to solve it, but the biggest difficulty is that on my PC I can't make it happen. Can you tell me if the error is sporadic, or does it always happen? Is there a particular procedure with which you can make it happen?

Hi
I write a new SerialUSB wrapper to comunicate with the engraver, that replace microsoft implementation that has some bug like the one reported here.

If you want you can test by download from here: https://github.com/arkypita/LaserGRBL/releases/download/v3.8.10/install.exe and enable UsbSerial2 connection protocol (before connect!).
