23H2 -> 25H2 and HBS

[JayDee]

I killed any HBS I could find in Task Manager... still could not disconnect the USB

Note: I usually run HBS from a non-admin account (elevated of course)
        I tried running from an admin account and I was able to disconnect the usb.
        So it seems to be related to permissions.
        This issue did not arise before the switch to 25H2

        BTW when I started HBS from the non-admin account, I tried switching to the
        admin account after the backup completed to try the disconnect. It did
        not succeed.
