We started having this problem (opening Settings/Display) after the Windows 11 August update for Enterprise. Every model of Dell that we have is having the issue. Tried BIOS updates, graphics driver updates and nothing seems to work.
You open it up and a blue circle just spins. You can click within the blank page and items do show up but its a crap shot what will come up. Been working on this most of the week and its stopping our Windows 11 migration until we get this figured out.
Note: Installing the September update didn't fix the problem. I think a lot of other users are having this problem but it hasn't been reported enough to rise to the top.
