Excad2 hangup and stalls Freezes up


I got a 50w fiber laser. have the laser connected to a windows 11 computer. Bought a bigger new computer with windows 11.

Now the laser hangs up in middle of engraving. When I power down laser or plug the usb the excad2 program goes back to normal.

And ideas, I’ve tried to

Reinstall windows

Switch off antivirus

Let ezcad2 throught firewall

Use only 2.0 usb hub

Switch video cards

All windows update
