I can confirm this bug too. The new software release fixes the camera cooling issue, but my filter wheel EFW2 cannot be reached by SGP. I will report this as well.
Edit: I take that back. I disconnected the camera and filter wheel and rebooted my laptop. When I reconnected the camera and filter wheel post reboot, the filter wheel works fine. Please try a reboot and reconnect. This worked for me.
