Can't calibrate camera in Luban in 4.8.2

When I try to calibrate the camera in my 10W laser on my SM2.0 A350, I can’t fine tune it in Luban? When I press calibrate I can move the corners of the square but as I try to accept the the result Luban just doesn’t react. Also the “preview” window is empty - it’s just grey and doesn’t show anything.

This is a huge problem. I tried to calibrate my machine because I had trouble reaching the corners of the cutting plate. But now I can’t use the camera at all…

Im on Mac btw…
