SB3 screen shuts off intermittently

[tuchas]

I've been having this issue with my SB3 where the screen goes black randomly. It usually comes back on after a minute or two but it's annoying as heck. When I detach the tablet from the base it comes right back on as well. I have seen some mentions of this when I googled this issue but there doesn't seem to be any resolution. Thoughts?

I am suspecting an issue with Cortana from builds since around January 14, 2021. Try disabling Cortana completely, and see if the problem goes away.
