Run auto focus causes Object reference not set to an instance of an object

Upgraded to 3.1.0.426 and had successful autofocus runs, then all of a sudden clicking on auto focus run gave Object reference not set to an instance of an object and SGP exit repeatedly.

focuser appeared to be moving OK under SGP/focus lock command.

Tried downgrading to 3.1.0.405 and it would just silently exit when pressing run.

I don’t recall exactly how I recovered but I know I cleaned all USB connections and rebooted.

Log files:

I’m assuming some usb issue, but it that case it would still be nice in SGP would report vs. bail out.

Thanks

This has already been addressed in 427

What do you mean with 427?
I have the same problem from time to time.
The auto focus is failing and the download of the subs are also not working then.
