I'm not sure which update broke this but looking at the GitHub for Notepad++ I see a few issues logged.
It seems they are creating the context menu for both classic and modern.
I can use the "modify" to remove the greyed-out one, but then I need to use the "Open with" sub-menu.
Do I need to add it manually then?

Re: Notepad++ is greyed out Win11
I ended up using the modify vis="Normal". From the issues reported, it didn't sound like that was an option.
