Agreed that the problem probably resides there. On all three installation efforts I have been exceptionally carefully to not touch anything until the full installation finishes. I see the black

Mine is checked as well but there’s actually a button to click to reconfigure. Says “Now”. Not sure why it worked for me but I was stumped as well. Just something to try.,,
