Two Trees TTC450 with Easel,USB not recognized once spindle is turned on

Hello, as per the title I have a cnc ttc450 and I use Easel free for the moment, if I click on the carve button with the spindle off the machine starts working but when I turn on the spindle easel it no longer recognizes the usb port

I got same problem. I tried Resetting , I tried changing to Design that worked before and all the time same issue it stops once spindle moves and pressing carve it stops. It is not my cnc machine for sure as it works off other software fine. So it has to be something to do with Easel or its Driver which i also reinstalled in case. SO if anyone has answer pls let us know.
