After the Win11 update "2023-10 Update for Windows 11 Version 22H2", I ran into the USB "sleep" issue disconnecting the system. Once that was corrected, a new problem emerged trying to run AutoFlat.vbs for dawn flats (log below). This is the same flat plan that I have used for dawn flats for months.

The problem is only with dawn flats. The same flat plan works if run at dusk.
