Thanks Sonny for taking the time.
Same here.
No such problem with my MS account or a new local user account I created for experimentation.
Just the hidden admin account.
I can right click and choose "Search" and type
Settings
And get to the settings and stuff like that, but cannot launch any modern app from the hidden admin account, like "Photos" "Weather", "Music", etc.,. Maybe the whole start menu is considered a "Modern App".
