It happens irrespective of whether or not a Basler camera is plugged in and on two different Windows 10 computers. I'm using the latest version of both Bonsai and pylon Viewer, but have also tried downgrading pylon Viewer to an older version with no success. I don't know what else to try - can anyone here help..?
