Settings and internet are fine. I dunno what to tell you. Very frequently Windows update shows its head, like I’ll randomly want to restart my computer because I installed a piece of software that required it, and then it kicks off a long round updates when I just want to use my computer.
I still think having to leave it on and let it run in the background is still just addressing the symptoms. An update process should be way faster than that so that such a thing isn’t needed.
